Final answer:
To simplify the expression, follow the order of operations. The simplified expression is -9 - x. To simplify the expression, we need to follow the order of operations (PEMDAS/BODMAS). Let's start by simplifying the expression inside the square brackets.
Step-by-step explanation:
To simplify the expression, we need to follow the order of operations (PEMDAS/BODMAS). Let's start by simplifying the expression inside the square brackets:
3 - 4(x - 5) = 3 - 4x + 20 = 23 - 4x
Next, simplify the expression inside the second set of square brackets:
3 - 7(x + 2) = 3 - 7x - 14 = -11 - 7x
Now, substitute these simplified expressions back into the original expression:
2(23 - 4x) - (-11 - 7x) = 46 - 8x + 11 + 7x = -9 - x
So, the simplified expression is -9 - x.
