Follow the ax + by + c formula

ax = -3x (because both has x)
by =  y 
c =  7 (it is the constant)

-3x + y + 7 is your answer

follow the y = mx + b formula

2y = 6x + 12

2(y) = 2(x + 6)
y = x + 6 is your answer

hope this helps

Hello!

You can only add variables with the same base and exponent

8u^3 + 4u^3 = 12u^3
8u^2 + 0 = 8u^2
0 + -6u = -6u
6 + 3 = 9

Put the sums together

12u^3 + 8u^2 - 6u + 9

The answer is D) 12u^3 + 8u^2 - 6u + 9

Hope this helps!
