Answer:
x=-9,y=-4
Step-by-step explanation:
2x-3y=-6...(1)
-2x-2y=26...(2)
To solve we will have to eliminate one of the given variables, the variable to be eliminated is x
And it can be done by adding up (1) and (2)
It gives
-5y=20
Divide both sides by-5
y=-4
Then substitute the value of y into (1)
2x-3(-4)=-6
2x+12=-6
Substrate 12 from both sides
2x=-18
Divide both sides by 2
x=-9
Therefore x gives -9 and y gives-4
Answer:
C
Step-by-step explanation:
<span>You have to convert rates to the same units before you compare them otherwise you are not comparing like with like. For example, if you compare 3kg with 3000g you may think the second is bigger, but when converted to the same rates they are actually identical.</span>
The answers are overall different. But there are similarities. Both equations have an addition sign. Both also have double digit numbers being added together.
