REARRANGING FORMULAE 2

1 Make x the subject of the formula ax – bx = c factorise divide both sides by (a – b)

2 Make x the subject of the formula ax + b = 5x + 4 collect xs on one side factorise divide both sides by (a – 5)

3 Make x the subject of the formula a(x − 5) = b(x + 2) expand the brackets collect xs on one side factorise divide both sides by (a – b)

4 Make x the subject of the formula multiply both sides by x − y expand the brackets collect the xs on one side factorise divide both sides by (f – 2y)

5 Make x the subject of the formula square both sides multiply both sides by c − x expand the brackets collect the xs on one side factorise divide both sides by (1 + b2)

6 Make x the subject of the formula multiply both sides by x collect the xs on one side factorise divide both sides by (c – b)
