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
