Let's solve the equation step by step:
3(x - 7) - x = 2x - 21
First, distribute the 3:
3x - 21 - x = 2x - 21
Combine like terms:
2x - 21 = 2x - 21
Subtract 2x from both sides:
-21 = -21
The equation simplifies to -21 = -21, which is true for any value of x. Therefore, this equation has infinitely many solutions.
