Answer 1

Answer:

x = 2, y = -1

solution is given in attachment. Please refer

Answer 2

Step-by-step explanation:

3x-1/y = 7 ........eq1

x+1/y = 1 ...........eq2

now, adding both the equations

you will get

4x = 8

x = 2

now you have to put the value of x in any equation

so you will get

x + 1/y = 1

2 + 1/y = 1

2y + 1/y = 1

2y + 1 = y

2y - y = -1

y = -1
