1 Make x the subject Re-arrranging equations

2 Its all about opposites Inverses as we like to call them

3 If you make something the subject then…. It will be on the left hand side of the equation and equal to something

4 Make a the subject of v = u + at Take u from each side v – u = at Then divide by t v – u = a t

5 But it isnt a = …. So flip it

6 v – u = a t flipped gives us a = v – u t

7 Make x the subject of v 2 = u 2 +2ax Take away u 2 v 2 - u 2 = 2ax Divide by 2a v 2 - u 2 = x 2a

8 Flip it! x = v 2 - u 2 2a
