if you add 35 to twice a number, the result is 17. What is the number?

A number is represented by a variable, let's call it "x".

Twice a number means we multiply by 2 --> 2x

Add 35
2x + 35

Now set that entire expression equal to 17
2x + 35 = 17

Plug that into the search engine to solve for x
x = -9
