Question

Solve for a. 5a - 2 = 23 a = ?

Answer 1

5a - 2 = 23.

First, take 5a - 2 = 23 and add 2 to each side

5a - 2 = 23
     +2    +2
5a = 25

now, divide each side by 5

5a = 25
/5      /5

a = 5

Answer 2

Solution

1) Add 2 to both sides
5a=23+2

2) Simplify 23+2 to 25
5a=25

3) Divide both sides by 5
a= $\frac{25}{5}$

4)Simplify $\frac{25}{5}$ to 5
a=5

ANSWER = 5
