**Math Riddles with Answers: Solution**

**Answer: Blue Fish = 3 and Red Fish = -2**

**Explanation:**

**We shall refer to the Blue Fish as X and Red Fish as Y.**

Let us look at the equations in a mathematical way.

**9X – 11Y = 49 ………………. (Equation 1)**

**13X – 12Y = 63 ……………….. (Equation 2)**

We will solve the question using the elimination method.

We will have to make the X- coefficients the same by eliminating the terms with 'X'.

We will multiply equation (1) with 13 and equation (2) with 9, and then we will subtract equation (2) from (1).

=> 13 x (9X – 11Y) = (49) x 13 ………. Equation 1

=> 9 x (13X – 12Y) = (63) x 9 ……….. Equation 2

We get,

=> 117X – 143Y = 637

=> 117X – 108Y = 567

Let us subtract these both equations. (We shall subtract the LHS of Equation 1 from the LHS of Equation 1 and RHS of Equation 2 from the RHS of Equation 2).

=> 117X – 143Y - (117X – 108Y) = 637 -567

=> 117X – 143Y – 117X + 108Y = 70

Both 117X and -117X cancel each other.

We now get:

=> -143y +108y = 70

=> -35y = 70

=> y = -2

Now, let us put the value of Y in equation (1) and solve to find the value of X

=> 9X – 11Y = 69

=> 9X- 11(-2) = 49

=> 9X +22 = 49

=> 9X = 49 -22

=> 9X = 27

=> X = 3

**Therefore, the values of X (which is Blue Fish) is 3 and Y (which is Red Fish) -2 respectively.**
