2y+x=-15
x=3y
2y+(3x)=-15
2y + (3*3y) = -15
11y=-15
y = -15/11

4x+7y=19
y=x+9
4x+7(x+9)=19
4x + 7x + 63 = 19
11x = -44
x = -4

y=6x+11
2y-4x+14
2(6x+11)-4x+14

2x-8y=6
y=-7-x
2x-8(-7-x)=6

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

Answer:

X = -1

Y = -2

Step-by-step explanation:

−4x+3y=−2                  

  y=x−1

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

-4x + 3x -3 = -2

-x = 1

x = -1

y = -1 -1

y -2

I also did it on khan an I got it right
