Question

8x + 17- 2x -9 =?? ,

7y - 10y + 11 =??

I want someone to answer and explain very clear and well, cuz I'm so bad on algebra.

Answer 1

Explanation:

So for the first one 8x is similar to -2x so you put them together and get 6x and posiative 17 and -9 are similar so you put those together and get 8 so the first eqaution is 6x+8 and for the second one 7y and 10y are similar also know as like terms so you put those together and get -3y becuase the seven is before the 10y and so the equation is -3y+11
