2-Solve 3(x+6)-4=6 x +2

X?

Required:

To simplify the given equation

Explanation:

\begin{gathered} 6x-4y+3x+8y \\  \\ group\text{ like terms} \\  \\ =6x+3x-4y+8y \\  \\ Add\text{ similar elements:} \\  \\ =9x-4y+8y \\  \\ Add\text{ similar elements} \\  \\ =9x+4y \end{gathered}\begin{gathered} 3\left(x+6\right)-4=6x+2x \\  \\ Add\text{ similar elements} \\  \\ 3\left(x+6\right)-4=8x \\  \\ expand \\  \\ 3x+14=8x \\  \\ subtract\text{ 14 from both sides} \\  \\ 3x+14-14=8x-14 \\  \\ 3x=8x-14 \\  \\ subtract\text{ 8x from both sides} \\  \\ 3x-8x=8x-14-8x \\  \\ -5x=-14 \\  \\ =divide\text{ both side by 5} \\  \\ \frac{-5x}{-5}=\frac{-14}{-5} \\  \\ x=\frac{14}{5} \end{gathered}
