Question

I know it’s not -2 please help!!

Answer 1

`\boxed { - 4}`

Explanation:

Substitute y = x-4 in the first equation.

`3x - 2(x - 4) = 4`

Distribute -2 in the expression.

`3x - 2x + 8 = 4 \\ x = 4 - 8 \\ x = - 4`

Because we only want to find the value of x.

Therefore the answer is -4.
