Let

the length of second train = L m Time taken to cross each other

=

If y=3-x,find the value of y, when x=1,2,3,4,5

Answer:

y = 2, 1, 0, (-1) and (-2).

Step-by-step explanation:

Given: y = 3 - x

Find: y

Solution:

y = 3 - x

When x = 1.

y = 3 - x

y = 3 - 1

y = 2.

When x = 2.

y = 3 - x

y = 3 - 2

y = 1.

When x = 3.

y = 3 - x

y = 3 - 3

y = 0.

When x = 4.

y = 3 - x

y = 3 - 4

y = (-1).

When x = 5.

y = 3 - x

y = 3 - 5

y = (-2).

Therefore, the values of y are 2, 1, 0, (-1), and (-2).
