Step-by-step explanation:
Two equations of planes are given.
We have to find the equation of the line which is formed by intersection of these two planes in parametric form

Let us eliminate one variable
Multiply I equation by 5 and subtract II from 5 * I



Or 
Consider II equation
5x+y-z=4

Let z=z
x = \frac{3z-16}{16} and y = \frac{31z}{16}-1
