So
number in a=6000-2000x where x=number of hours
number in b=2000-1000x
when will a=b
so set them equal to each other and solve
6000-2000x=2000-1000x
subtract 6000 from both sdies
-2000x=-4000-1000x
add 1000x to both sdies
-1000x=-4000
multiply -1
1000x=4000
divide by 1000
x=4
in 4 hours, they will be the same, but, their numbers will be negative, so there is actually no real life time when they will be the same observe
1 hour: a=4000, b=1000
2 hour a=2000 b=0
3 hour a=0 b=-1000
4 hour a=-2000 b-=-2000
but you can't have -2000 cells, you can only have 0 or more than 0
Answer:
x= 3
Step-by-step explanation:
Simplify the equation:
3(2x-5)- 4x+8= -1 becomes 6x-15-4x+8= -1
Then, combine like terms.
6x-4x= 2x
-15+8= -7
So now your equation becomes 2x-7= -1
Now, we need to isolate our variable (x).
Add 7 to both sides.
-7+7 cancels out and -1+7= 6
and now you have 2x=6
To solve for x, you need to divide by 2 on both sides and you get an answer of 3.
x= 3
