Answer: The simplified expression is 6x - 23
Step-by-step explanation: To simplify the expression (12x-13)-2(3x+5) we will follow the order of operations:
First, we simplify the inner parentheses: 2(3x+5) = 6x + 10
Next, we substitute this simplified version back into the original expression: (12x-13)-(6x+10)
Now we can simplify the expression by combining like terms: 12x-13-6x-10 = 6x - 23
So the simplified expression is 6x - 23
