this will be for the con assignment equations with parentheses okay so there's only one variable in these equations we're just going to have to use uh distributive property all right so i'm going to rewrite this equation first on the left we have 10 p minus 3. and on the right we're going to have to distribute so this 2 is multiplied by both terms inside the parentheses so we're going to do 2 times 12 that's 24 and we're going to do 2 times 4p okay 2 times 4 is 8 and we still have the p and finally we have minus seven okay now you want to combine like terms so there's nothing to combine on the left but on the right hand side we have a 24 and a negative seven so 24 minus seven that's just 17 and we still have our positive 8p okay and finally you want to get letters on one side and numbers on the other so here we have positive 8p and i am going to do minus 8p on both sides 10p minus 8p is 2p and bring down your negative 3. bring down your 17 and 8p minus 8p cancels all right and in order to get the negative 3 to cancel we're going to do the opposite which is positive 3. you do it to both sides bring down your 2p negative 3 plus 3 cancels and 17 plus three is twenty okay dividing both sides by two the twos cancel and p is twenty over two which is just ten all right and that goes in the box so i think most of these are going to be the same okay so if i had to write out the steps it would be to first distribute okay and then the second one would be combine like terms and the third step would be numbers on one side and letters on the other side okay so you just want to separate the numbers and letters all right so here we go first step is to distribute so i'm going to rewrite this equation all right and this 3 is multiplied by both terms inside the parentheses so we're going to do 3 times 6 that's 18. and we're gonna do three times negative f that's gonna be negative three f oh we still have minus four made a little mistake minus four on the right we have three f minus four okay so we did the distributing now we want to combine like terms 18 and negative 4 that gives us positive 14 minus 3f and that's going to equal 3f minus 4. okay and we want to get letters on one side and numbers on the other so i'm going to move the negative 3f over here by doing a positive 3f and i want to move the negative 4 over to this side by doing a positive 4. okay always do the same to both sides fourteen plus four that's eighteen negative three f plus three f that's zero bring down the equal sign three f plus three f is six f and negative four plus four is zero okay dividing both sides by six the sixes cancel eighteen over six is just three so f equals three all right so like i said distribute and then combine like terms and then finally get letters on one side and numbers on the other all right one more so let's rewrite this we have negative t equals and on the left on the right we need to distribute this nine is multiplied by both numbers inside the parentheses so nine times t it's just nine t and nine times negative ten is negative ninety okay so combining like terms there's nothing to combine on either side okay you can't do nine t minus twenty so the final step you can't combine 19 minus 90 minus 90. so the final step letters on one side numbers on the other okay so i have a negative 90 over here i want to get rid of nine t so i'll do minus nine t on both okay negative t minus nine t this is the same as negative one t all right and if you do negative one minus nine that's negative ten and you still have t okay nine t minus nine t cancels and you bring down your negative 90. solving for t we just divide both sides by negative 10. and it cancels over here negative 90 over negative that's just nine so you put it in the box
