Answer:
(- 1, 1 )
Step-by-step explanation:
2x - 3y = - 5 → (1)
3x + y = - 2 → (2)
multiplying (2) by 3 and adding to (1) will eliminate y
9x + 3y = - 6 → (3)
add (1) and (3) term by term to eliminate y
11x + 0 = - 11
11x = - 11 ( divide both sides by 11 )
x = - 1
substitute x = - 1 into either of the 2 equations and solve for x
substituting into (2)
3(- 1) + y = - 2
- 3 + y = - 2 ( add 3 to both sides )
y = 1
solution is (- 1, 1 )
