The answer is 36 in simplist form
So,
We know that we cannot add or subtract quantities of the same kind.
-18xy can only be added/subtracted to 4yx, which is the same as 4xy. The result would be -14xy, or -14yx.
The correct option is B.
2 = 2????
Thats what Im getting it from.
Since x is 2 then it would still be 2=2 in simple term.
