< 6
Answer:
Step-by-step explanation:
2x-4y=12.........(1)
-x+2y=-6..........(2)
Multiply equation (2) by 2
-2x + 4y = -12........(3)
Adding (3) from (1)
2x + (-2x) - 4y + 4y = 12 + (-12)
2x - 2x - 4y + 4y = 12 - 12
Ox -0y = 0
No solution
Answer:
(B)-x-(-x) =0
Step-by-step explanation:
<u>Option A</u>
Our equation is: -x +0+(- x) = 0
Left Hand Side:
-x +0+(- x) = -x-x=-2x

<u>Option B</u>
Our equation is: -x-(-x) =0
Left Hand Side:
-x-(-x) =-x+x=0

Therefore, the equation in Option B is true.
