54-35 + 2* (76-3*7)=?

Let's solve the expression step by step.

1. Start with the innermost parentheses: \[ 3 * 7 = 21 \] Therefore, the expression inside the parentheses becomes: \[ 76 - 21 = 55 \]

2. Now replace that in the original expression: \[ 54 - 35 + 2 * 55 \]

3. Next, calculate \( 2 * 55 \): \[ 2 * 55 = 110 \]

4. Now replace that in the expression: \[ 54 - 35 + 110 \]

5. Next, do the subtraction: \[ 54 - 35 = 19 \]

6. Finally, add: \[ 19 + 110 = 129 \]

So the final result is: \[ \boxed{129} \]
