Answer:

15 $x^{2}$ + 7x + 12

Step-by-step explanation:

(6x^2 + 7x + 2) - (-9x^2 - 10)

Flip the sign:

- (-9x^2 - 10) becomes + 9x^2 + 10

Combine like terms:

6x^2 + 7x + 2 + 9x^2 + 10

6x^2 + 9x^2 = 15x^2

2 + 10 = 12

Put it all together:

15x^2 + 7x + 12

Start with adding 3x to both sides to get y=3x+1
