Answer:
(5, 7 )
Step-by-step explanation:
4x + y = 27 → (1)
5x - y = 18 → (2)
adding the 2 equations term by term will eliminate y
9x + 0 = 45
9x = 45 ( divide both sides by 9 )
x = 5
substitute x = 5 into either of the 2 equations and solve for y
substituting into (1)
4(5) + y = 27
20 + y = 27 ( subtract 20 from both sides )
y = 7
solution is (5, 7 )
