    On this sheet, all answers start with x = \dots. Do not include the x = in your answer. For example if your answer is x = 2y - t, just write 2y - t.

    Make x the subject in the expressions below.

  1. yx + m = q
  2. ax - q = y
  3. x^{2} = p
  4. \displaystyle{\frac{x}{z}} - b = h
  5. h\left( x - b \right) = c
  6. y\sqrt{x} = p
  7. bx^{2} - c = m
  8. \displaystyle{\frac{ax - b}{p}} = p
  9. Rearrange these more difficult formulae to make x the subject:

  10. yx + m = q
  11. ax - q = y
  12. x^{2} = p
  13. \displaystyle{\frac{x}{z}} - b = h
  14. h\left( x - b \right) = c
  15. y\sqrt{x} = p
  16. bx^{2} - c = m
  17. \displaystyle{\frac{ax - b}{p}} = p
