Answer:
x = 62 , y = 22
Step-by-step explanation:
given the sum of x and y is 84 and their difference is 40 , then
x + y = 84 → (1)
x - y = 40 → (2)
add (1) and (2) term by term to eliminate y
(x + x) + (y - y ) = 84 + 40
2x + 0 = 124
2x = 124 ( divide both sides by 2 )
x = 62
substitute x = 62 into either of the 2 equations and solve for y
substituting into (1)
62 + y = 84 ( subtract 62 from both sides )
y = 22
The larger number, x is 62 and the smaller number, y is 22
