Please help me solve the equations please and thank you

Answer 1

(3, - 1 )

Explanation:

y = x - 4 → (1)

y = - x + 2 → (2)

Substitute y = x - 4 into (2)

x - 4 = - x + 2 ( add x to both sides )

2x - 4 = 2 ( add 4 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into (1)

y = 3 - 4 = - 1

solution is (3, - 1 )
