    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. c - z = y (make z the subject)
  2. y - c = z (make c the subject)
  3. b - qa = c (make a the subject)
  4. z - ya = p (make a the subject)
  5. c = b - px (make x the subject)
  6. x = q\left( b - p \right) (make p the subject)
  7. Change the subject in the equations below.

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

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