Answer:
The answer for the first problem is 10x + 4 and the answer for the second problem is 14x + 6.
Step-by-step explanation:
First problem: 6x - 3 + x + 7 + 3x
- First, look at the terms, match the x's with x's and numbers with numbers.
6x + 3x + 1x = 10x
-3 + 7 = 4
So this makes the answer 10x + 4.
Second problem: 2(7x + 3)
All you need to do is distribute the 2 for 7x + 3, meaning that you multiply each of them by 2.
2 times 7x = 14x
2 times 3 = 6
So the answer is 14x + 6.
