Question

Solve this system of equations

Y=2x
X = -y + 6

Answer 1

(2, 4 )

Explanation:

Given the 2 equations

y = 2x → (1)

x = - y + 6 → (2)

Substitute x = - y + 6 into (1)

y = 2(- y + 6) ← distribute

y = - 2y + 12 ( add 2y to both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Substitute y = 4 into (2) for corresponding value of x

x = - 4 + 6 = 2

solution is (2, 4 )
