  1. Solve the system of equations. \begin{align*} q - 4 v &= -1\\ q + 3 v &= -1 \end{align*}
    $v = $

    $q = $

  2. Solve the system of equations. \begin{align*} 2 t &= y - 2\\ - y &= - 4 t - 4 \end{align*}
    $t = $

    $y = $

  3. Solve the system of equations. \begin{align*} s &= 4 a + 1\\ - 2 a - 2 s &= -2 \end{align*}
    $s = $

    $a = $

  4. Solve the system of equations. \begin{align*} a &= 4 p - 3\\ p &= 3 a - 2 \end{align*}
    $a = $

    $p = $
