40-2\left(7-3x\right)=30-\left(3-7x\right)-5\left(x+1\right)
Multiply both sides of the equation by 10, the least common multiple of 5,10,2.
40-14+6x=30-\left(3-7x\right)-5\left(x+1\right)
Use the distributive property to multiply -2 by 7-3x.
26+6x=30-\left(3-7x\right)-5\left(x+1\right)
Subtract 14 from 40 to get 26.
26+6x=30-3-\left(-7x\right)-5\left(x+1\right)
To find the opposite of 3-7x, find the opposite of each term.
26+6x=30-3+7x-5\left(x+1\right)
The opposite of -7x is 7x.
26+6x=27+7x-5\left(x+1\right)
Subtract 3 from 30 to get 27.
26+6x=27+7x-5x-5
Use the distributive property to multiply -5 by x+1.
26+6x=27+2x-5
Combine 7x and -5x to get 2x.
26+6x=22+2x
Subtract 5 from 27 to get 22.
26+6x-2x=22
Subtract 2x from both sides.
26+4x=22
Combine 6x and -2x to get 4x.
4x=22-26
Subtract 26 from both sides.
4x=-4
Subtract 26 from 22 to get -4.
x=\frac{-4}{4}
Divide both sides by 4.
x=-1
Divide -4 by 4 to get -1.
