Simplify the algebraic expression by combining like terms.

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

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.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
