Eliminate the parameter. x = 7t, y = t + 4

Solution:

Given expression is: 

x = 7t, y = t + 4

Let us proceed with x value,

x = 7t

t = x/7

y = t + 4

Since t = x/7

y = x/7 + 4

7y = x + 28

Thus the parameter is eliminated.

Eliminate the parameter. x = 7t, y = t + 4

Summary:

Eliminating the parameter. In x = 7t, y = t + 4 we get 7y = x + 28
