Question

What could be the coefficient of x once the variable term is isolated on one side of the equation? Check all that apply.

3x - 6(5x + 3) = 9x + 6

1. Distribute: 3x - 30x - 18 = 9x + 6

2. Combine like terms: -27x - 18 = 9x + 6
–36
–27
–24

36

Answer 1

-36,36

Explanation:

3x - 6(5x + 3) = 9x + 6

Distribute:

3x - 30x - 18 = 9x + 6

Combine like terms:

-27x - 18 = 9x + 6

There are two possible ways to isolate x

On the left

Subtract 9x from each side

-27x - 18 -9x = 9x-9x + 6

-36x -18 = 6

On the right

Add 27x from each side

-27x - 18 +27x = 9x+27x + 6

-18 =36x+ 6
