Answer:

Step-by-step explanation:
1. Regroup terms.

2. Add 1 to both sides.

3. Simplify 3x + 3 + 1 to 3x + 4.

4. Subtrect 3x from both sides.

5. Simplify 4x - 3x to x.

Therefor, the answer is, x = 4.
The GCF of the three terms (9a, -18b and 21c) is 3
Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c
So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)
Answer: 3(3a - 6b + 7c)
If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
