Question

How do you solve `20+25x=345`?

Answer 1

`x = 13`

Explanation:

First subtract 20 from both sides:

`20 (-20) + 25x = (-20)`
`25x = 325`

This gets x as the only term on the left hand side.
Divide both sides by the co-effcient of x (25), so that you find the answer for 1 x.

`(25x)/25 = 325 / 25`
`x = 13`
