3x + y = -4 3x - 4y = 6​

Mathematics
1 answer:
erastova [34]3 years ago
6 0

Answer:

(-1, -2) or x=-1 y=-2

Step-by-step explanation:

3x+y=-4      (1)

3x-4y=6      (2)

i used the first equation to subtract the second this cancels out the x

and you are left with:

5y=-10

y=-2

plug this back in:

2x+(-2)=-4

2x-2=-4

add 2 to both sides:

2x=-2

x=-1
