Answer:
Step-by-step explanation:
plug y into the first equation:
8x+5y=24
8x+5(-4x)=24
8x-20x=24
-12x=24
x=-24/12
x=-2
then plug x to the second equation
y=-4
y=-4(-2)
y=8
x=-2
y=8
The answer is 1908 1/3 or 5725/3
So, let's make these two values improper fractions so they're easier to work with.
So, to get the rate he grew in those months we have:
