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
