Answer 1

Answer:

this is ur answer and y is equals to 3..

Answer 2

Answer:

7x-2y=1. 1

3x+4y=15. 2

Step-by-step explanation:

let multiply 1st equation by 2

14x-4y=2. 3

adding secondand third equation

14x-4y=2

+3x+4y=15

17x=17

x=1

therefore let substitute x=1 in2 equation

3×1+4y=15

4y=18

y=9/2
