Answer:

(6, - 9 )

Explanation:

Given the 2 equations

6x + 2y = 18 → (1)

- 4x - 2y = - 6 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

2x + 0 = 12

2x = 12 ( divide both sides by 2 )

x = 6

Substitute x = 6 into either of the 2 equationsand solve for y

Substituting into (1)

6(6) + 2y = 18

36 + 2y = 18 ( subtract 36 from both sides )

2y = - 18 ( divide both sides by 2 )

y = - 9

solution is (6, - 9 )
