question solve. 3(2x + 4) = 30

Explanation:

Step1: Expand the left - hand side

$3(2x + 4)=6x+12$, so the equation becomes $6x + 12=30$.

Step2: Subtract 12 from both sides

$6x+12 - 12=30 - 12$, which simplifies to $6x = 18$.

Step3: Divide both sides by 6

$\frac{6x}{6}=\frac{18}{6}$, so $x = 3$.

Answer:

$x = 3$
