well, say you have the number 4, and you want to multiply it with 5, but you want 4 to be an unknown factor. X x 5= 20 X=4
The 'X' indicates that the factor is unknown.
His birthday is unknown.
If one factor is 48 and the other is unknown, divide both sides of the equation by 48. 48 x ? = 4608 ? = 96
The answer depends on the exact nature of the puzzle.
divide the known factor into the product if stated x times 8 = 72 x = 72 divided by 8 x = 9
At this stage the reason for rheumatoid factor is still unknown.

It usually involves some kind of dividing. Take a basic problem like n x 5 = 45, where n is the unknown factor. Divide both sides of the equation by 5 so that n stands alone. 45 divided by 5 is 9, so n = 9
