Answer:
C
Step-by-step explanation:
Given the 2 equations
6x + 2y = 8 → (1)
12x + y = 22 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 24x - 2y = - 44 → (3)
Add (1) and (3) term by term, thus eliminating y
- 18x = - 36 ( divide both sides by - 18 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
6(2) + 2y = 8
12 + 2y = 8 ( subtract 12 from both sides )
2y = - 4 ( divide both sides by 2 )
y = - 2
Solution is (2, - 2 ) → C
