Question

3x+6=-4x-29 I give up my brains

Answer 1

The given equation is

$3x+6=-4x-29$

First, we add 4x on each side.

$\begin{gathered} 3x+4x+6=-4x+4x-29 \\ 7x+6=-29 \end{gathered}$

Then, we subtract 6 from each side.

$\begin{gathered} 7x+6-6=-29-6 \\ 7x=-35 \end{gathered}$

At last, we divide the equation by 7.

$\begin{gathered} \frac{7x}{7}=-\frac{35}{7} \\ x=-5 \end{gathered}$

Hence, the solution is x = -5.
