Given that: step 1


3x+12=8x-18

step 2: subtract 3x both side


\begin{gathered} 3x+12-3x=8x-3x-18 \\ 12=5x-18 \end{gathered}

Step 3: Add 18 both side:


\begin{gathered} 12+18=5x-18+18 \\ 30=5x \end{gathered}

Step 4: divide both side by 5


\begin{gathered} (30)/(5)=(5x)/(5) \\ 6=x \end{gathered}

Step:6 The value of x is:

x=6
