2+5+ 3x + 1 + 2x =
5x+2+5+1 =
5x+7+1 =
5x+8

5x+8

Step-by-step explanation:

2+5+ 3x + 1 + 2x

Combine like terms

3x+2x     + 2+5+1

5x          +8

Yes

Step-by-step explanation:

To simplify an expression like the one, you have to collect all the like terms and do the operation individually for each group of like terms.

In 2+5+3x+1+2x, the like terms are:

2,5,1 and 3x,2x

Solve them individually.

2+5+1=8

3x+2x =5x.

Put the, back and the final answer is 5x+8
