-3-10-2x+3x=7x+5-4x
Use the distributive property to multiply -2 by 5+x.
-13-2x+3x=7x+5-4x
Subtract 10 from -3 to get -13.
-13+x=7x+5-4x
Combine -2x and 3x to get x.
-13+x=3x+5
Combine 7x and -4x to get 3x.
-13+x-3x=5
Subtract 3x from both sides.
-13-2x=5
Combine x and -3x to get -2x.
-2x=5+13
Add 13 to both sides.
-2x=18
Add 5 and 13 to get 18.
x=\frac{18}{-2}
Divide both sides by -2.
x=-9
Divide 18 by -2 to get -9.
