Eight plus the quotient of a number and 3 is −2
8 + (x/3) = - 2
Hope it helps
-10 and -2
Because -10-2= -12 and -10 x -2 = 20
Hope this helps :)

Micah did not explain the last step correctly. You cannot cross out a term from the numerator and denominator unless it is a factor. In other words, x² needed to be multiplied and not added in order to cross it out.
Are you looking for the amount after interest gained? If so I believe the answer would be $40.
500 x 0.04 x 2 = 40
