Answer:

The lines don't intercept

Explanation:

we have


3y=4x-6

isolate the variable y

Divide by 3 both sides


y=(4)/(3)x-(6)/(3)

simplify


y=(4)/(3)x-2 -----> equation A


8x-6y=-30

Isolate the variable y


6y=8x+30

Divide by 6 both sides


y=(8)/(6)x-(30)/(6)

simplify


y=(4)/(3)x-5 -----> equation B

Compare equation A and equation B

The slopes are the same and the y-intercepts are different

Remember that

If two lines has the same slope, then the lines are parallel

therefore

In this problem line A and line B are parallel lines

The system of equations has no solution, because the lines don't intercept
