Step 1 is wrong it should be: 2x - 3x - 1=3
So you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3
subtitute x=3 into first equation (y=3x)
y=3(3)
y=9
Answer:
-89
Step-by-step explanation:
15 fish* (1 ft^3/ 0.3 fish)= 50 ft^3.
(Note that the unit cancels out so you get the answer)
The volume of the tank is 50 ft^3~
