To solve the equation 120 - X + 2X + 2X = 180, combine like terms:
- X + 2X + 2X = 3X
Therefore, the equation becomes:
120 + 3X = 180
To solve for X, subtract 120 from both sides of the equation:
3X = 180 - 120
3X = 60
Finally, divide both sides of the equation by 3 to isolate X:
X = 60 / 3
X = 20
Therefore, the value of X is 20.
