This is a problem of one unknown variable
The equation given is:
[tex]-\frac{6}{5}x=-36[/tex]First, we should notice that both sides of the equation are negative, so we can multiply by -1 on each side in order to have positive terms
[tex]\frac{6}{5}x=36[/tex]
then we need to isolate the x
[tex]\begin{gathered} 6x=5\cdot36 \\ 6x=180 \\ x=\frac{180}{6} \\ x=30 \end{gathered}[/tex]x=30
