Answer:
x = 7, y = 60
Step-by-step explanation:
Given the 2 equations
50x - 2y = 230 → (1)
50x - 3y = 170 → (2)
Subtract (2) from (1) term by term on both sides
y = 60
Substitute y = 60 into either of the 2 equations and evaluate for x
Substituting into (1)
50x - 2(60) = 230
50x - 120 = 230 ( add 120 to both sides )
50x = 350 ( divide both sides by 50 )
x = 7
