Answer:

x=-8

Step-by-step explanation:

I always change the decimals into whole numbers by multiplying them by 10.  If you do this, it is much easier to solve.  All you do is multiply every term by 10.

the equation changes to

-5(x+3)-2x=41

-5x-15-2x=41

combine like terms

-7x-15=41

bring the 15 over to the 41

-7x=56

divide everything by 7

-x=8

change x to a positive

x=-8
