Answer:
(0, - 3 )
Explanation:
Given the 2 equations
6x - 4y = 12 → (1)
- 6x + y = - 3 → (2)
Add (1) and (2) term by term to eliminate x, that is
0 - 3y = 9
- 3y = 9 ( divide both sides by - 3 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for y
Substituting into (1)
6x - 4(- 3) = 12
6x + 12 = 12 ( subtract 12 from both sides )
6x = 0 , thus
x = 0
solution is (0, - 3 )
