Answer:

(c) he subtracted by 6x instead of adding 6x on both sides

Explanation:

You want to know the mistake in the solution of the equation ...

-2(3x -5) = 4(x +3) +8

Solution

The solution should proceed like this:

-2(3x -5) = 4(x +3) +8

-6x +10 = 4x +12 +8 . . . . . . . use the distributive property

-6x +10 = 4x +20 . . . . . . . . . . combine like terms

10 = 10x +20 . . . . . . . . . . . . . . . add 6x (Andre did this wrong)

-10 = 10x . . . . . . . . . . . subtract 20

-1 = x . . . . . . . . . . . divide by 10

The choice that best describes Andre's error is ...

he subtracted by 6x instead of adding 6x on both sides
