Question

Create an expression equivalent to 4(2x−3)−6x+7 using the least number of terms.

Answer 1

2x-5

Explanation:

First solve for the parenthesis:

4(2x-3) = 8x-12

8x-12-6x+7

Change all minus signs to plus signs:

8x+-12+-6x+7

Now you can use the communicative property to move the terms around:

8x+-6x+-12+7

Then change all "+-" to "-"

8x-6x-12+7

8x-6x=2x

-12+7=-5

2x-5
