Answer:

x = 3

Step-by-step explanation:

Given

5x - 3 = 12 ( add 3 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

As a check

Substitute x = 3 into the left side of the equation and if equal to the right side then it is a solution.

5(3) - 3 = 15 - 3 = 12 = right side

Thus x = 3 is the solution
