solve 3(x+3) = 18

1 answer

To solve the equation \( 3(x + 3) = 18 \), follow these steps:

  1. Start by dividing both sides by 3 to simplify: \[ x + 3 = \frac{18}{3} \] \[ x + 3 = 6 \]

  2. Next, subtract 3 from both sides to isolate \( x \): \[ x = 6 - 3 \] \[ x = 3 \]

So, the solution is \( x = 3 \).
