find x2 and x3 which r second parametric equation??

The first set of parametric equations

x1=7t+4

x2=t7

x3=8t5

and the second set of parametric equations

describe the same line in 3.

Solution

x1=7t+4

x1= 7s

7t+4=7s

7t=4-7s

t=(4-7s)/7

x2=t7

x2=((4-7s)/7)7

x2=((7s-4)/7)7

x2=s -(4/7)7

x2=s -(53/7)

x3=8t5

x3=8((4-7s)/7)5

x3=(32/7) -8s -5

x3=(-3/7) -8s

finally

x1= 7s

x2=s -(53/7)

x3=(-3/7) -8s
