-31-4x=-5-5-25x
Use the distributive property to multiply -5 by 1+5x.
-31-4x=-10-25x
Subtract 5 from -5 to get -10.
-31-4x+25x=-10
Add 25x to both sides.
-31+21x=-10
Combine -4x and 25x to get 21x.
21x=-10+31
Add 31 to both sides.
21x=21
Add -10 and 31 to get 21.
x=\frac{21}{21}
Divide both sides by 21.
x=1
Divide 21 by 21 to get 1.
