Question

The sum of two numbers is 47. The greater number is 9 more than the smaller number. Which equation can be used to solve for the smaller number? x + (x + 9) = 47 x − (x + 9) = 47 x(x + 9) = 47 x(x − 9) = 47

Answer 1

x + (x + 9) = 47

Explanation:

This equation can be used to solve for

This equation can be used to solve forthe smaller number.

Answer 2

I believe the correct answer from the choices listed above is the first option. The equation that can be used to solve the problem would be x + (x + 9) = 47.

The sum of two numbers is 47. ---> x + y = 47 where x is the smaller number and y is the larger.

The greater number is 9 more than the smaller number. -----> y = x + 9

x + ( x + 9 ) = 47
