Question

The sum of two numbers is 72. The greater number is 8 more than the smaller number. Which equation can be used to solve for the smaller number? (1 point)


x(x − 8) = 72

x − (x + 8) = 72

x + (x + 8) = 72

x(x + 8) = 72

Answer 1

$x + (x + 8)$

Answer 2

x+y=72
x-y=8

different terms add
similar signs subtract
2x+y-y=80
2x=80
x=40
y=32
