    On this sheet, all answers start with x = \dots. You must include the x = in your answer: for example x = 2y - t.

    Change the subject in the equations below.

  1. q - y = p (make y the subject)
  2. z - q = y (make q the subject)
  3. q - ca = p (make a the subject)
  4. c - yq = z (make q the subject)
  5. z = p - yx (make x the subject)
  6. c = y\left( a - p \right) (make p the subject)
  7. Change the subject in the equations below.

  8. x = \displaystyle{\frac{y}{c}} (make c the subject)
  9. \displaystyle{\frac{c}{x}} + b = a (make x the subject)
  10. c + \displaystyle{\frac{y}{z}} = x (make z the subject)
  11. Mix it up: change the subject in the equations below.

  12. b = yq + c (make q the subject)
  13. b = \displaystyle{\frac{1}{3}}z + a (make z the subject)
  14. p - ca = z (make a the subject)
  15. c = \displaystyle{\frac{z}{y}} - p (make y the subject)
  16. a = czq -y (make z the subject)
  17. bx^{2} -p = q (make x the subject)
