4x%2B20=x%2B26 Start with the given equation.



4x=x%2B26-20 Subtract 20 from both sides.



4x-x=26-20 Subtract x from both sides.



3x=26-20 Combine like terms on the left side.



3x=6 Combine like terms on the right side.



x=%286%29%2F%283%29 Divide both sides by 3 to isolate x.



x=2 Reduce.
