Answer:
Step-by-step explanation:
3x-4y=65
3x=65+4y
x=(65+4y)/3, when y=4
x=(65+4*4)/3
x=(65+16)/3
x=81/3
x=27
Answer:
The answer is A trust me.

To reverse the inequality multiply by -1 on both sides.


Now solve the next inequality
.
Add 9 on both sides.


Divide by 2 on both sides.


Combine the inequality.

Option D is the correct answer.
