Question

please answer me


X =2 and y=-3​

Answer 1

3x+4y=-1

& 2x-y=6

now, use substitution

y=2x-6

& put it in 1st equation

it will be

3x+4(2x-6)=-1

-> 3x+8x-24=-1

-> 11x=23

so x=23/11

& y=2×23/11-6

-> (46-66)/11

-> -20/11

Answer 2

Answer:

3x+4y=--6

2x-y=6

on adding both equation

5x+3y=0

at x=2

y=-10/3

at y=3

x=-9/5
