First to do is simplify the equation by removing the parentheses.
This is done by using the distributive property.
equals
so you have to multiply by
Now the equation looks like this:

Next combine like terms. So -40 combines with -5 to become -45 like so:

Next move all the terms with x to one side of the equal sign and
all terms without x to the opposite side of the equal sign.
To this add 45 to both sides of the equal sign like so:


Now to solve for x divide both sides of the equal sign by -2

-2x divided by -2 leaves x and -16 divided by -2 is 8
so
now check the answer by replacing x with 8 in the original equation.

-40-(2x+5)=-61
get rid of parenthesis: -40-2x-5=-61
combine: -2x-45=-61
add 45 to both sides:-2x=-16
divide -2 into each side: x=8
Check:
-40-(16+5)=-61
-40-21=-61
