5\left(x-1\right)+40=4x
Multiply both sides of the equation by 20, the least common multiple of 4,5.
5x-5+40=4x
Use the distributive property to multiply 5 by x-1.
5x+35=4x
Add -5 and 40 to get 35.
5x+35-4x=0
Subtract 4x from both sides.
x+35=0
Combine 5x and -4x to get x.
x=-35
Subtract 35 from both sides. Anything subtracted from zero gives its negation.
