Question

5.) $-8x - (-2x) =$
6.) $-6x - 2x =$
7.) $-5x - (-2x) =$
8.) $9x - 12x =$
9.) $-8x - 8x =$
10.) $6x - (-4x) =$

Explanation:

Problem 5: $-8x - (-2x) =$

Step 1: Simplify the double negative

Subtracting a negative is like adding the positive, so $-(-2x) = +2x$. The expression becomes $-8x + 2x$.

Step 2: Combine like terms

Combine the coefficients of $x$: $-8 + 2 = -6$. So the result is $-6x$.

Step 1: Combine like terms

Subtract the coefficients of $x$: $-6 - 2 = -8$. So the result is $-8x$.

Step 1: Simplify the double negative

Subtracting a negative is adding the positive, so $-(-2x) = +2x$. The expression becomes $-5x + 2x$.

Step 2: Combine like terms

Combine the coefficients: $-5 + 2 = -3$. So the result is $-3x$.

Answer:

$-6x$

Problem 6: $-6x - 2x =$
