Simplify each term.
10x−20−11=4+3x

Add −20 and −11 to get −31.
10x−31=4+3x

Move 3x to the left-hand side of the equation by subtracting 3x from both sides.
10x−31−3x=4

Add 10x and −3x to get 7x.
7x−31=4

Since −31 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 31 to both sides.
7x=31+4

Add 31 and 4 to get 35.
7x=35

Divide each term in the equation by 7.
