It's too hard for me to show all the work, but you can find a common denominator in 8.
Change 3/4 to 6/8 and -3/2 to -12/8.
Now that all the fractions have the same denominator, you can multiply the whole problem by 8 and cancel out all denominators.
You are left with 6=3x-12
Add 12 to 6 and cancel out on the right side.
18=3x
Divide by 18 by 3
x=6
Easy
equation is
f(x)=2ˣ
where x=number of hours elapsed
after 6 hours
f(6)=2⁶=64 bacteria
to solve for 1024
1024=2ˣ
take ln of both sides
ln(1024)=ln(2ˣ)
ln(1024)=x(ln(2))
divide both sides by ln(2)
ln(1024)/ln(2)=x
using calculator
10=x
or you could recognize that
1024=2¹⁰
or keep divising 1024 by 2
10 hours for 1024 bacteria
