Question

Y = - x + 2 and Y = 4
what is the sloution

Answer 1

(- 2, 4 )

Explanation:

given

y = - x + 2 and y = 4

since we are given the value of y, then substitute y = 4 into the other equation, that is

4 = - x + 2 ( subtract 2 from both sides )

4 - 2 = - x + 2 - 2 ( simplify )

2 = - x ( multiply both sides by - 1 )

2 × - 1 = - x × - 1 , that is

- 2 = x

solution is (- 2, 4 )
