Question

Help pls. Solve the system of linear equations by substitution.

Answer 1

(5, 3)

Explanation:

`x = 17 - 4y \\ y = x - 2`

Substitute x into y:

`y = (17 - 4y) - 2 \\ y = 15 - 4y \\ y + 4y = 15 \\ 5y = 15 \\ y = 3`

Substitute y into x:

`y = x - 2 \\ 3 = x - 2 \\ 3 + 2 = x \\ x = 5`

Therefore your answer is (5, 3).
