And the negative of that would be
Answer:
Step-by-step explanation:
-2x + 3y = 6.....(x, -4)...so y = -4
-2x + 3(-4) = 6
-2x - 12 = 6
-2x = 6 + 12
-2x = 18
x = -18/2
x = -9
so the value of x is -9.....(-9,-4)
Answer:
system 4.
Step-by-step explanation:
3x+6y=9
multiply by 2
6x+12y=18 ....(1)
-2x+-4y=4
multiply by 3
-6x-12y=12 ...(2)
add (1) and (2)
0+0=30
which is impossible .It has no solutions.
