Step-by-step explanation:
If you add a number that is negative, you are basically subtracting it.
This means that
Since they both have the same denominator, you can easily subtract the fractions:
Let the capacity of bus be x students
And van be y students, now ;
From the given statements we get two equations ~
multiply the equation (2) with 2 [ it won't change the values ]
Now, deduct equation (1) from equation (3)
Therefore each bus can carry (x) = 45 students
Now, plug the value of x in equation (1) to find y ~
Hence, each van can carry (y) = 17 students in total.
