Answer:
(52, 32 )
Step-by-step explanation:
Given the 2 equations
y = x - 20 → (1)
x + y = 84 → (2)
Substitute y = x - 20 into (2)
x + x - 20 = 84, that is
2x - 20 = 84 ( add 20 to both sides )
2x = 104 ( divide both sides by 2 )
x = 52
Substitute x = 52 into (1) for corresponding value of y
y = 52 - 20 = 32
Solution is (52, 32 )
