The first step for solving this equation is to collect the like terms with an x variable on the left side of the equals sign.
20x - 6 - 5 = x + 11 + 4x
Calculate the difference between -6 and -5.
20x - 11 = x + 11 + 4x
Collect the like terms with x on the right side of the equation. 
20x - 11 = 5x + 11
Move the variable to the left side of the equation and then change its sign.
20x - 5x - 11 = 11
Now move the constant to the right side and change its sign.
20x - 5x = 11 + 11
Collect the terms on the left.
15x = 11 + 11
Add the numbers on the right side.
15x = 22
Lastly,, divide both sides of the equation by 15 to find your final answer.
