40-5\left(x+3\right)=4\left(1-x\right)
Multiply both sides of the equation by 20, the least common multiple of 4,5.
40-5x-15=4\left(1-x\right)
Use the distributive property to multiply -5 by x+3.
25-5x=4\left(1-x\right)
Subtract 15 from 40 to get 25.
25-5x=4-4x
Use the distributive property to multiply 4 by 1-x.
25-5x+4x=4
Add 4x to both sides.
25-x=4
Combine -5x and 4x to get -x.
-x=4-25
Subtract 25 from both sides.
-x=-21
Subtract 25 from 4 to get -21.
x=21
Multiply both sides by -1.
