Given:
[tex]x=4y+3,y=4+t[/tex]Required: Parametric equation of y.
Explanation:
Substitute 4+t for y into the equation of x.
[tex]\begin{gathered} x=4(4+t)+3 \\ =16+4t+3 \\ =4t+19 \end{gathered}[/tex]So, the parametric equation for x is x = 4t+19.
Final Answer: The parametric equation of x is x = 4t + 19.
