9x + 7 = 52

Question

`9x + 7 = 52`

Answer 1

Hey!

Let's switch the equation around:

`52 - 7 = 9x`

The sign changes when moved to the other sign. At first, it was (+), now it's (-).

First do 52 - 7

`52 - 7 = 45`

That leaves you with:

`45 = 9x`

Divide both sides by 9

`(45)/(9) = (9x)/(9)`

`\framebox{x = 5}`

Answer 2

Hey there! :)

9x + 7 = 52

Subtract 7 from both sides.

9x = 52 - 7

Simplify.

9x = 45

Divide both sides by 9.

9x ÷ 9 = 45 ÷ 9

Simplify.

x = 5
