Answer:
the numbers are 43 and 15
Step-by-step explanation:
Let the numbers are x and y
x+y=58
x-y=28
from that two equations,
2x=86
x=43
substitute x value in any equation we will get ,
y=15
Answer:
x = 43 and y = 28
Step-by-step explanation:
Consider two number x and y such that x + y = 58 and x - y = 28
from equation (2) x = y + 28
now, we substitute x by y + 28 in equation (1) we get:
x + y = 58 means y + 28 + y = 58 the. 2y + 28 = 58 then y = 30/2 = 15
since, x = y + 28 then x = 15 + 28 = 43
