Answer:
12
Explanation:
1. Write the problem.
(3x+6)-(3x-6)
2. Put a 1 after the subtraction/negative sign because there is technically a 1 after the subtraction/negative sign between the two phrases.
= (3x+6)-1(3x-6)
3. Distribute the -1 to the 2nd part.
= (3x+6) + (-3x+6)
4. Simplify the equation.
= 3x+6-3x+6
5. Find like terms.
= 3x+6-3x+6
The 3x and -3x cancel each other out, leaving 6+6.
So, the answer is 12.
