What's 17=2x+3x+7 so I can no do homework

17=2x+3x+7

We move all terms to the left:

17 - (2x+3x+7) = 0

We add all the numbers together, and all the variables

- (5x+7) + 17=0

We get rid of parentheses

-5x-7+17=0

We add all the numbers together, and all the variables

-5x+10=0

We move all terms containing x to the left, all other terms to the right

-5x=-10

x=-10/-5

x=2
