Final answer:
Upon simplifying both sides of the equation, the left side results in -14 and the right side results in 33. As these two values are not equal, the initial equation -1(8+6) = 7×5 + (-2) is not correct.
Step-by-step explanation:
The student's question is asking to verify if the given mathematical expression is correct: -1(8+6) = 7×5 + (-2). To solve this, let's first simplify each side of the equation separately.
The left side of the equation simplifies as follows:
- Multiply -1 by the sum of 8 and 6: -1 × (8 + 6) => -1 × 14 = -14
The right side of the equation simplifies as follows:
- Multiply 7 by 5: 7 × 5 = 35
- Add -2 to the product: 35 + (-2) = 35 - 2 = 33
Now, we compare the simplified results:
- Left side result: -14
- Right side result: 33
Since -14 does not equal 33, the original statement -1(8+6) = 7×5 + (-2) is incorrect.
