Answer:
(6.25, 0.5 )
Step-by-step explanation:
2x - y = 12 → (1)
2x + y = 13 → (2)
Add the 2 equations term by term to eliminate y
4x + 0 = 25
4x = 25 ( divide both sides by 4 )
x = 6.25
substitute x = 6.25 into either of the 2 equations and solve for y
substituting into (2)
2(6.25) + y = 13
12.5 + y = 13 ( subtract 12.5 from both sides )
y = 0.5
solution is (6.25, 0.5 )
