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.
