Hey there!
Let's solve this equation.
[tex]-6x-10=-40[/tex]
Add 10 to both sides.
[tex]-6x-10+10=-40+10=-6x=-30\\-6x=-30[/tex]
Divide both sides by by -6.
[tex]\frac{-6x}{-6} =\frac{-30}{-6}[/tex]
Simplify the fraction by dividing -30 by -6.
[tex]-30/-6=5\\ x=5[/tex]
x=5 is your answer.
Hope this helps!
