Answer:
121 and 57
Explanation:
let the 2 numbers be x and y with x > y , then
x + y = 178 → (1)
x - y = 64 → (2)
add (1) and (2) term by term to eliminate y
2x + 0 = 242
2x = 242 ( divide both sides by 2 )
x = 121
substitute x = 121 into (1) and solve for y
121 + y = 178 ( subtract 121 from both sides )
y = 57
the 2 numbers are 121 and 57
