The sum of two numbers is 76. Their difference is 36. Find the numbers
X+y= 76
X-y=36
Add x+x , y cancels out, add76+36
2x= 112
Divide 2 both sides
X= 61
Now substitute your x answer into first original equation
X+y =76
61+y =76
Subtract 61 both sides to get y .
Y= 76-61
Y= 15
Your two numbers are 61 and 15
