Answer 2

The correct answer is x = 3 and y = 7.

Given: The equation = 3x-y=2 and 5x-2y=1.

To Find: The value of x and y.

Solution:

The equation = 3x-y=2 and 5x-2y=1.

3x-y=2

y = 3x-2

Put the value of y in the second equation.

5x-2y=1

5x - 2(3x-2) = 1

5x - 6x + 4 = 1

x = 3

Now put the value of x in y = 3x-2.

y = 3(3) - 2

y = 9-2 = 7

Hence, the value of x is 3 and y is 7.
