Question

The sum of two numbers is 77. The greater number is 5 more than the smaller

number. Which equation can be used to solve for the smaller number?

O 1) x(x - 5) = 77
O2) x(x + 5) = 77
3) x + (x + 5) = 77
4) x + (x + 5) = 77

Answer 1

`x+(x+5)=77`

Explanation:

Let's assume that the two numbers are x and y, with y being the larger number.

According to the statement,
`x+y=77`, and
`y=x+5`

By substituting the values, we get:

`x+(x+5)=77\\`
