Question

Solve for xxx. 12x+7 4012x+7 40

Answer 1

`x = 2.75`

Explanation:

I'm assuming you have an equation

`12x + 7 = 40\\`

and you want to solve for x.

This is easy. First, subtract 7 from each side of the equation.

`12x+7-7 = 40-7`

`12x = 33`

Then divide both sides by 12, to get x alone on the left side.

`(12x)/(12) = (33)/(12)`

`x = (33)/(12) = 2.75`
