Answer:
9d + 7
Step-by-step explanation:
(6d + 5) - (2 - 3d)
= (6d - (-3 d))+ (5 - 2)
= (6d + 3d) + 3
= 9d + 3
X+ (x+2)+ (x+4)= -21
3x+6=-21
3x=-27
x=-9
Final answer: -9, -7, -5

(I saw in the top left corner of the picture that this is for Algebra II. I am in 8th grade, currently taking geometry, and I haven't taken Algebra II yet, but I <em>did</em> take Algebra I last year. I am 95% sure this is correct but if it isn't, the I sincerely apologize.)
No, this is an equation which you are to solve.
Add 12 to both sides of the equation: y = 19+12, or y = 31 (solution).
(3x2 + 7y) (2x2 – 3x + 9)
=(6+7y)(-3x+13)
=-18x+78-21xy+91y
