-10x+20+3x-\left(-x+2\right)=5-\left(3x+1\right)+2\left(-4x-1\right)
Use the distributive property to multiply 5 by -2x+4.
-7x+20-\left(-x+2\right)=5-\left(3x+1\right)+2\left(-4x-1\right)
Combine -10x and 3x to get -7x.
-7x+20-\left(-x\right)-2=5-\left(3x+1\right)+2\left(-4x-1\right)
To find the opposite of -x+2, find the opposite of each term.
-7x+18-\left(-x\right)=5-\left(3x+1\right)+2\left(-4x-1\right)
Subtract 2 from 20 to get 18.
-7x+18-\left(-x\right)=5-3x-1+2\left(-4x-1\right)
To find the opposite of 3x+1, find the opposite of each term.
-7x+18-\left(-x\right)=4-3x+2\left(-4x-1\right)
Subtract 1 from 5 to get 4.
-7x+18-\left(-x\right)=4-3x-8x-2
Use the distributive property to multiply 2 by -4x-1.
-7x+18-\left(-x\right)=4-11x-2
Combine -3x and -8x to get -11x.
-7x+18-\left(-x\right)=2-11x
Subtract 2 from 4 to get 2.
-7x+18-\left(-x\right)+11x=2
Add 11x to both sides.
4x+18-\left(-x\right)=2
Combine -7x and 11x to get 4x.
4x-\left(-x\right)=2-18
Subtract 18 from both sides.
4x-\left(-x\right)=-16
Subtract 18 from 2 to get -16.
4x+x=-16
Multiply -1 and -1 to get 1.
5x=-16
Combine 4x and x to get 5x.
x=\frac{-16}{5}
Divide both sides by 5.
x=-\frac{16}{5}
Fraction \frac{-16}{5} can be rewritten as -\frac{16}{5} by extracting the negative sign.
