hjlf3 years ago
8 0

Answer:

\boxed { - 4}

Step-by-step 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.

A. subtract the bottom equation from the top equation

Step-by-step explanation:

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.
