Answer:
(6, - 9 )
Step-by-step 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 )
