Answer:

Step-by-step explanation:

3x - 4y = -7........(equation 1)

5x - 2y = 0.........(equation 2)

Multiplying (equation 2) by 2

The resultant is

10x - 4y = 0........(equation3)

Now subtracting (equation 1) from (equation3)

Now the result is

7x = -7

x = -7/7

x = -1

Now putting the value of x in (equation 1)

3x - 4y = -7

3(-1) - 4y = -7

-3 - 4y = -7

-4y = -7 + 3

-4y = -4

y = -4/-4

y = 1

Hence value of x is -1 and value of y is 1 through elimination method
