Example: 2 5/2 multiply the bottom number 2 by the whole number 2 and add the top number 5, the bottom number (2) will always stay the bottom number so it would be 9/2
Let x be the unknown quantity. First, cross multiply to get 56x=392. Then divide both sides of the equation by 56 to get x=7.
(1,2,-1) is the answer i got.
2 x 7 is 14. Add the b to the end. The answer is 14b.
