To solve the equation \( 3( x + 7 ) = 42 \), follow these steps: 1. Distribute the 3 on the left side: \[ 3x + 21 = 42 \] 2. Subtract 21 from both sides: \[ 3x = 42 - 21 \] \[ 3x = 21 \] 3. Divide both sides by 3: \[ x = \frac{21}{3} \] \[ x = 7 \] So, the solution is \( x = 7 \).

To solve the equation \( 3( x + 7 ) = 42 \), follow these steps:

Distribute the 3 on the left side: \[ 3x + 21 = 42 \]
Subtract 21 from both sides: \[ 3x = 42 - 21 \] \[ 3x = 21 \]
Divide both sides by 3: \[ x = \frac{21}{3} \] \[ x = 7 \]

So, the solution is \( x = 7 \).
