friends please solve this
​

Answer 1

Answer:

-1

Step-by-step explanation:

4x+2y=6----(1 eqn)

-3x-y=-5------(2 eqn)

-3(4x+2y=6)

4(-3-y=-5)

-12-6y=-18

-12-4y=-20

(+) (+) (+)

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

0 -2y=2

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

-2y=2

y=-2/2

y=-1

Answer 2

4x+3y=6~equation1

-3x-y=-5~equation2

So,eq1=eq2×2

4x+2y=6

-6x-2y=-10

=-2x=-4

X=2

Equating the value of x in equation 1

4×2+2y=6

2y=-2/2

y=-1
