Answer:

Group and add the x coefficients (factoring)

Add the other numbers: 3 and -15

2x + 3 + 5x – 15 = 2x + 5x + 3 – 15 = 7x - 12

Answer:

Explanation:

2x+3+5x-15

I can start off by combining like terms (2x and 5x with 3 and -15)

2x+5x+3-15

and my new equation will be 7x-12. Since they are not like terms (15 does not have x so I can't continue solving), 7x-15 will be my final answer.
