Answer 1

Answer:

what I ur question bro...... can't understand......

Answer 2

Step-by-step explanation:

Let us take x=blue fish, y=red fish

9x-11y=49=>equation 1

13-12y=63=>63

now from equation 1,we get :x=49+11y/9

substituting this value in equation two gives you:13(49+11y/9)-12y=63

537+143y-108y=63

35y=-474

y=-474/35=>-13.5

X=49+11(-13.5)/9=>37.5
