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

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

  12. q = ax + y (make x the subject)
  13. q = \displaystyle{\frac{1}{2}}c + z (make c the subject)
  14. y - zp = q (make p the subject)
  15. x = \displaystyle{\frac{b}{a}} - q (make a the subject)
  16. a = cqp -x (make q the subject)
  17. by^{2} -c = x (make y the subject)
