Multi step equation that equal 27 when solved

Sample Equation:  3x - 3 = 27

Multiple step:

3x    -  3  =    27
        + 3       +3  Step1. Remove the -3 by adding 3 to both sides
3x            =   30
÷3                ÷ 3  Step2. Remove the multiplicand 3 by dividing both sides by 3
x              =  10

To check: substitute x by its value

3x - 3 = 27
3(10) - 3 = 27
30 - 3 = 27
27 = 27
