To simplify the expression \((34x - 1) + (34x - 2)\), you can follow these steps:
- Combine the like terms (the \(34x\) terms and the constant terms).
Starting with the \(34x\) terms: \[ 34x + 34x = 68x \]
Now, combining the constant terms: \[ -1 + (-2) = -1 - 2 = -3 \]
Putting it all together: \[ 68x - 3 \]
Thus, the simplified expression is: \[ \boxed{68x - 3} \]
