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
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.
