Best ResponseYou've already chosen the best response.1First, combine like terms on both sides of the equal sign. Like terms are terms that have the same variable. On the left side, combine 3x and 5x. On the right side, combine 7 and 15.

Best ResponseYou've already chosen the best response.1\( \color{red}{3x} + 1 + \color{red}{5x} = \color{green}{7 +15} + 7x\) \(\color{red}{3x + 5x} + 1 = \color{green}{7 +15} + 7x\) What is 3x + 5x = ? What is 7 + 15 = ?

Best ResponseYou've already chosen the best response.1\(\color{red}{8x } + 1 = \color{green}{22} + 7x\) So far we combined the like terms on the left and we combined the like terms on the right. Ok so far?

Best ResponseYou've already chosen the best response.1Now we want all terms with x on the left side, and all plain numbers on the right side. Since there the term 7x on the right side, we subtract 7x from both sides. dw:1441819900908:dw

Best ResponseYou've already chosen the best response.1Correct. Now we want all plain numbers on the right side, so we subtract 1 from both sides. dw:1441820102435:dw
