The system of equations is x+ y = 360, y = 8x, which represents that Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as the angelfish option, the first is correct.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish.
x represents the number of angelfish Nancy bought and
y represents the number of goldfish she bought
From the problem:
x+ y = 360
y = 8x
Thus, the system of equations is x+ y = 360, y = 8x, which represents that Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as the angelfish option, the first is correct.
