Given the equation 6x + 18 = 72:
Solve the equation showing all work.
To solve the equation 6x + 18 = 72, we need to isolate the variable x on one side of the equation.
First, we subtract 18 from both sides of the equation:
6x + 18 - 18 = 72 - 18
6x = 54
Next, we divide both sides of the equation by 6 to solve for x:
(6x)/6 = 54/6
x = 9
Therefore, the solution to the equation 6x + 18 = 72 is x = 9.
