Question

Solve for x:15 = 3(x - 2) + 3

Answer 1

hello

$15=3(x-2)+3$

to solve this problem, let's follow some steps

step 1

multiply through the bracket by it's coefficient

$\begin{gathered} 15=3(x-2)+3_{} \\ 15=3x-6+3 \end{gathered}$

step 2

add through and collect like terms

$\begin{gathered} 15=3x-3 \\ 15+3=3x \\ 18=3x \end{gathered}$

step 3

divide both sides by 3

$\begin{gathered} 18=3x \\ \frac{18}{3}=\frac{3x}{3} \\ x=6 \end{gathered}$

x = 6
