Question

Five times the sum of a number and 6 is 45. What is the number?

Answer 1

`x=3`

Explanation:

`5(x+6)=45`

(I'm using `x` as the variable to solve for in this equation)

use distribution
`5x+30=45`

then subtract
`45-30=15`

then divide to solve for `x`

`15 div 5 = 3.`
therefore, `x=3.`
