Answer:
The numbers are 12 and 36
Step-by-step explanation:
x + y = 48
x - y = 24
Add y to both sides of the equation
x = 24 + y
Substitute new value for x into first equation
24 + y + y = 48
Add y's together
24 + 2y = 48
Subtract 24 from both sides of the equation
2y = 24
Divide both sides of the equation by 2
y = 12
48 - 12 = 36
The numbers are 12 and 36
