one method for solving 3 (x - 4) = 18 is to divide by 3, then add 4. which method would also result in the correct answer?

Answer 1

Another method to solve the equation \( 3 (x - 4) = 18 \) is to start by distributing the 3 on the left side of the equation:

1. Distribute the 3: \[ 3x - 12 = 18 \]

2. Add 12 to both sides: \[ 3x - 12 + 12 = 18 + 12 \] \[ 3x = 30 \]

3. Finally, divide by 3: \[ x = \frac{30}{3} = 10 \]

So, the method of distributing the 3 first and then solving for \( x \) also results in the correct answer.
