Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
x - 2y = - 4 → (1)
2x + y = 7 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
4x + 2y = 14 → (3)
Add (1) and (3) term by term to eliminate y, that is
5x = 10 ( divide both sides by 5 )
x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
2(2) + y = 7
4 + y = 7 ( subtract 4 from both sides )
y = 3
Solution is (2, 3 )
