Question

The sum of five and two times a number is 23. What is the number?

Answer 1

5+2x=23 | x=9

Explanation:

We would begin by using the Subtraction Property of Equality to isolate the variable (Subtract 5 from both sides.). Our product would now be 18. Then, we would use the Division Property Of Equality to isolate the 2 from the x (Divide 2 on both sides.). We would be left with x=9.
