Answer:
b
Step-by-step explanation:
I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)
First one: 3x+9+8x + 12
Collect like terms and simplify
(3x+8x)+(9+12)
11x+21
Second one: 2x + 6+x² + 6x + 9
Collect like terms and simplify
8x+15+
Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

4(x+5)=9x + 4x - 34 (given)
4x + 20 = 9x + 4x - 34 (distributive property)
4x + 20 = 13x - 34 (combine like terms)
20 = 9x - 34 (subtraction property of equality)
54 = 9x (subtraction property of equality)
x=6 (division property of equality)
