-2x-10+3=2-3\left(x+1\right)
Use the distributive property to multiply -2 by x+5.
-2x-7=2-3\left(x+1\right)
Add -10 and 3 to get -7.
-2x-7=2-3x-3
Use the distributive property to multiply -3 by x+1.
-2x-7=-1-3x
Subtract 3 from 2 to get -1.
-2x-7+3x=-1
Add 3x to both sides.
x-7=-1
Combine -2x and 3x to get x.
x=-1+7
Add 7 to both sides.
x=6
Add -1 and 7 to get 6.
