  • Make x the subject of 4x - 3y = 12
    • x = 3y + 12
    • x = \frac{12 + 3y}{2}
    • x = \frac{12 + 3y}{4}  ✓
  • Make p the subject of \frac{p}{2} + q = 7
    • p = -2(q - 3.5)
    • p = -q - 7
    • p = 2(7-q)  ✓
  • Make a the subject of 3a -\frac{b}{4} + 2 = 0
    • a = \frac{b - 4 }{12}
    • a = \frac{b - 8 }{4}
    • a = \frac{b - 8 }{12}  ✓
