Write the Following Four Restrictions in the Form Rβ = $\frac { \beta _ { 3 } } { \beta _ { 1 } }$

Essay

Write the following four restrictions in the form Rβ = r, where the hypotheses are to be tested simultaneously.
β₃ = 2β₅,
β₁ + β₂ = 1,
β₄ = 0,
β₂ = -β₆.
Can you write the following restriction β₂ = - $\frac { \beta _ { 3 } } { \beta _ { 1 } }$ in the same format? Why not?
