Answer 1

Answer:

x=65/119 and y=24/17

Step-by-step explanation:

you can even check my answer by substitute the values in calculators and check.

Answer 2

Answer:

let assume 7x-2y=1 as a equation one

and multiple by 2

14x-4y=2

3x+4y=7

-----------------

17x =9

x=9/17

x=0.53

then substitute The value of x in equation one

7 (0.53) - 2y = 1

3.7 - 2y = 1

-2y = 1 - 3.7

-2y = -2.7

y = 2.7/2

y = 5.4

Therefore x=0.53 & y=5.4
