Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 3 → (1)
x + 6y = - 3 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the term in x, that is
- 2x - 12y = 6 → (3)
Add (1) and (3) term by term to eliminate x
- 9y = 9 ( divide both sides by - 9 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (2)
x + 6(- 1) = - 3
x - 6 = - 3 ( add 6 to both sides )
x = 3
Solution is (3, - 1 )
