Answer:
(5, 3 )
Explanation:
5x + y = 28 → (1)
x - y = 2 → (2)
adding (1) and (2) term by term will eliminate y
(5x + x) + (y - y) = 28 + 2
6x + 0 = 30
6x = 30 ( divide both sides by 6 )
x = 5
substitute x = 5 into either of the 2 equations and solve for y
substituting into (1)
5(5) + y = 28
25 + y = 28 ( subtract 25 from both sides )
y = 3
solution is (5, 3 )
