Five less than twice a number is 23. What is the number ?

Let the number be x.

Twice the number is therefore 2x.

2x - 5 = 23

Add 5 to each side of the equation.

2x - 5 + 5 = 23 + 5

-5 + 5 = 0

23 + 5 = 28

2x = 28

Divide each side by 2

2x/2 = 28/2

x = 14


Check:

2x - 5 = 23

2(14) - 5 = 23

28 - 5 = 23



Answer:

x = 14
