Question

In the equation 6x – 2 = –4x + 2, Spencer claims that the first step is to add 4x to both sides. Jeremiah claims that the first step is to subtract 6x from both sides. Who is correct?

Answer 1

both correct

Explanation:

6x-2=-4x+2 add 4x

10x-2=2 add 2

10x=4

6x-2=-4x+2 sub 6x

-2=-10x+2 sub 2

-4=-10x multiply -1

4=10x
