Answer: 59 & 21
Step-by-step explanation:
so this probably won't be the best explanation, but here goes:
For the sake of knowing the two numbers aren't equal to each other, I decided to do variables n and x, so:
n+x=80
Now we need to find the value of n:
So the question sets this up as
n-2x=17. We need to change the equation so that we're solving for n, so: n=17+2x
Next we need to solve n+x=80, to do that we need to make it into x=80-n
Now that they're set up like this we can do : 80-n=17+2x.
I honestly don't know how to explain it the rest of the way but if you plug in those two numbers they should be right.
Decimal form= 7.5 , fraction form = 15/2 , improper fraction= 7 and 1/2
