Someone please explain to me how it turned from 5x to 10x.

Both sides were divided by 1/2.

Step-by-step explanation:

To further simplify the equation, both sides were divided by 1/2.

5x = 1/2[10 + (8x - 2)]

10x = 10 + 8x - 2 (As you can see, 5x / 1/2 = 10x and 1/2[10 + (8x - 2)] = 10 + 8x - 2)

10x = 8x + 8

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
