Solve for x: 1/5 (5x + 12) = 18

Answer 1

To solve for x, we can start by isolating the variable on one side of the equation.

First, let's simplify the equation:

1/5 (5x + 12) = 18

The 1/5 coefficient can be eliminated by multiplying both sides of the equation by 5:

5 * (1/5) (5x + 12) = 5 * 18

This simplifies to:

5x + 12 = 90

Now, let's isolate x by moving the constant term to the other side of the equation:

5x = 90 - 12

5x = 78

Finally, divide both sides by 5 to solve for x:

x = 78/5

x = 15.6
