Question

Solve 5y-7x=0 and 2y-3x=-6

Answer 1

Answer:

7x-5x=0 so 2x=0 so X=2

Step-by-step explanation:

this is your answer

Answer 2

Answer:

x=30,y=42

Step-by-step explanation:

5y-7x= 0 --> equation 1

2y-3x= -6 --> equation 2

Multiplying equation 1 by 2 and equation 2 by 5, we get

10y - 14x = 0

10y- 15 x = - 30

(on subtracting)

x=30(Ans)

Putting value of x in equation 2 we get,

2y - 3x= -6

2y - 90= -6

2y = 84

y= 42(Ans)
