The answer may be 1 or ∞. Mathematically, the answer is one as no matter how you place them, the pairs will still look the same. But there is many ways you can put the b***s in such as doing it normally, throwing it in, etc. Also, stop swearing because it is annoying.

If you do

 \(n\over{0}\)

then it will turn into an imaginary number. I do not mean '\(i\)

as it only means \(\sqrt-1\).

2nd way: calculate it for yourself.

Math is not lame. For example, you go to the shops. They don't have a calculator and can't do math very well. Calculate the money. You can prove stuff by calculation and math is always correct.

I cannot answer this question because I don't know what a gf is.

2x-y=-14→-4x+2y=28

3x+2y=-7

Subtract the equations:

-7x=35

x=-7

Subsitute:

-14-y=-14

y=0

Off topics are not possible to calculate 

There is nothing equivalent to i. i is just a number line on a 2 Dimension number line.

You're using decimal system so 2x10=20
