There is only one solution, which is: x = 7
Steps to solve:
Use the distributive property to multiply anything inside the parenthesis by 3.
3x - 3 x 2 =
3x - 6 = 22 - x
Move the variable on the right side to the left side and change the sign.
3x + x - 6 = 22
Move the constant on the left to the right and change its sign.
3x + x = 22 + 6
Gather like terms.
4x = 22 + 6
Add the numbers.
4x = 28
Divide both sides of the equation by 4.
x = 7
