Answer 1

Step-by-step explanation:

value of x is 9 and value of y is 17/11

Answer 2

Answer:

x = 3         y = 1

Step-by-step explanation:

2x - 7y = -1     eq.1

4x + 3y = 15    eq.2

eq.1 x2

4x - 14y = -2   eq.3

now eq.3 - eq.4

4x - 14y = -2

-(4x + 3y) = -(15)

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

-17y = -17

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

y = 1

Putting the value in eq.1

2x - 7(1) = -1

2x = -1 + 7

2x = 6

x = 3
