The sum of 2 numbers is 36
x + y = 36
:
the difference is 24.
x - y = 24
:
Use elimination here, add the two equations
x + y = 36
x - y = 24
--------------addition eliminates y, find x
2x = 60
x =
x = 30
:
Find y using x + y = 36
30 + y = 36
y = 36 - 30
y = 6
:
Check in the equation x - y = 24
30 - 6 = 24
