Given: 3x − 2y = 0
Add 2y to both sides to get: 3x = 2y
Divide both sides by 3 to get: x = 2y/3
Given: x > 4
Substitute above value of x to get: 2y/3 > 4
Multiply both sides of the inequality by 3 to get: 2y > 12
Divide both sides of the inequality by 2 to get: y > 6
Answer: E

3x-2y=0 and x>4.
Let x =5
15-2y=0
from here -2y must equal (-15)
y>6
