Question 183473

OK.
ONE APPROACH:
Let x=number of rockfish
then 24-x=number of bluefish
2.5x+8(24-x)=137 get rid of parens
2.5x+192-8x=137 subtract 192 from each side
2.5x+192-192-8x=137-192 collect like terms
-5.5x=-55
x=10------------------number of rockfish
24-x=24-10=14-------------number of bluefish
ANOTHER APPROACH:
Let x=number of rockfish
And let y=number of bluefish
x+y=24--------------------------------eq1
2.5x+8y=137-----------------------------eq2
You can solve
