Question

solve for x. 18 = 6x + 3x

Explanation:

Step1: Combine like terms

Combine the \(x\)-terms on the right side: \(6x + 3x = 9x\), so the equation becomes \(18 = 9x\).

Step2: Solve for \(x\)

Divide both sides by 9: \(\frac{18}{9}=\frac{9x}{9}\), which simplifies to \(2 = x\).

Answer:

\(x = 2\)
