Question

Susan begins counting backward from 1298 by 4's, saying one number every 5 seconds. At the same time, Jim begins counting forward from 171 by 3's, saying one number every 5

seconds. What number will they both say at the same time? (By the way I'm only in 6th grade so please explain well :)

Answer 1

We need to create an equation for this in terms of X.
Essentially 1298-(4 x unknown number) = 171 + (3 x unknown number)
We will call this unknown number X and we know that the unknown number is the same for both of them as they both say a number at 5 second intervals
