Since 8x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 8x from both sides.
4−3x−8x=7
Add −3x and −8x to get −11x.
4−11x=7
Move 4 to the right hand side of the equation by subtracting 4 from both sides.
−11x=−4+7
Add −4 and 7 to get 3.
−11x=3
Divide each term in the equation by −11.
x=−3/11
