Question

The sum of twice a number and 13 is 75

Answer 1

Greetings!

"The sum of twice a number and 13 is 75."...

Let's translate this into an equation:

`2x+13=75`
Solve for x:
Add -13 to both sides.

`(2x+13)+(-13)=(75)+(-13)`
Simplify.

`2x=62`
Divide both sides by 2.

`(2x)/2=(62)/2`
Simplify.

`x=31`

The variable is equal to 31.

Hope this helps.
