Answer:
(1, 2 )
Explanation:
Given the 2 equations
x + 4y = 9 → (1)
2x - 4y = - 6 → (2)
Adding (1) and (2) term by term will eliminate the y- term, that is
3x + 0 = 3
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (1)
1 + 4y = 9 ( subtract 1 from both sides )
4y = 8 ( divide both sides by 4 )
y = 2
solution is (1, 2 )
