6 0

Answer: (4,-4)

y=-4, x=4

Step-by-step explanation:

-4x=4y

4x-8y=12

-8y=-4x+12  Now I can substitute -4x for 4y

-8y=4y+12

-2y=y+12

-3y=12

y=-4

-4x=4y

-4x=4(-4)

x=4

How do i do this????
PSYCHO15rus [73]
What you do is you combine like terms... so in your instance it is using m.
9m+2= 3m-10
-3m      -3m
3m + 2 =-10
        +10 +10
3m= 12
m= 4
