Answer 2

Hello mate....❤

here is your answer..✌

Equ.1 - 2x+3y=-4

Equ.2 - x-y=6

x-y=6

x=6+y (sub. this 'x' in equ.1)

2(6+y)+3y=-4 (multiple 2 with (6+y))

12+2y+3y=-4 (add 2y+3y)

12+5y=-4 (subtract 12 on both sides)

12–12+5y=-4–12 (then it comes to)

5y=-16 (divide both sides with 5)

5y/5=-16/5

Y=-16/5 (we got 'y' value then put it on equ.1or.2)

x-(-16/5)=6 (- × - = +) we get

x+(16/5)=6 (subtract (16/5) on both sides)

x+(16/5)-(16/5)=6-(16/5)

X=((6×5)-16)/5

x=(30–16)/5

x=14/5.

The value of x=(14/5) & y=(-16/5).
