14 – Rearrange (make the subject)

Remember the balance – do the same thing to both sides of the equation.


Example 1:

Rearrange to make y the subject: x = y + 2

Subtract 2 from both sides, x –2 = y + 2 –2 or x – 2 = y


Example 2:

Make y the subject: 3x = 2y + 1

Subtract 1 from both sides, 3x – 1 = 2y

Divide both sides by 2 and y is:


Your Turn:

Make z the subject: 4y + 5 = 3z – 5
