Question

Please help me please

Answer 1

8x+10y

Explanation:

What you do first is you need to subtract -2y from 9y to get 7y.

So you have (12x+7y)-(4x-3y). The negative sign needs to be added into the problem so it will be (12x+7y)+(-4x+3y). You will then add and minus them together to get 8x+10y.

Answer 2

A 8x+10y

Explanation:

Sum of 12x+9y and -2y

12x+9y + -2y

12x +7y

Subtract 4x-3y from 12x+7y

12x+7y - (4x-3y)

Distribute the minus sign

12x+7y -4x+3y

8x +10y
