Question

(iv) 2x - y =3, x-3y=-1​

Answer 1

Answer:

x=(3-y)/2

x=-1-3y

comparing above

(3-y)/2=-1-3y

3-y=-2-6y

5y=-5

y=-1

x=-1+3

=2

Step-by-step explanation: hope you get it

Answer 2

Answer:

let (1) be 2x-y=3 and (2) be x-3y=-1

(1)x'2' => 2x-6y=-2

Subtracting (1) from (2)

2x-6y=-2

- 2x+ y =-3

=> -5y=-5

Therefore, y=5

Substituting value of y in (2)

x-3(5)=-1

=> x-15=-1

=> x=15-1

therefore, x=14

Hence x is 14 and y is 5.
