Algebra Rearranging Formulae Subject Appears Twice Youtube Sometimes the subject can appear on the same side of the equation, and s hazel and lesley show you how to rearrange formulas where the subject appears twice. For the next example we going to make x the subject of the equation. 2 – 3x = y 4x 1 if the subject appears twice in the equation you are likely to need to factorise once all the terms are on one side of the equation. 2 – 3x = y (4x 1) then clear the fraction. 2 – 3x = 4xy y then multiply out the brackets. Question type 5: formulas when the subject appears twice. in some instances the required subject will appear more than once in the given formula. in these examples we factorise the terms involving the subject. example: rearrange the following formula h=2\textcolor{blue}{r} g\textcolor{blue}{r} to make \textcolor{blue}{r} the subject. Rearranging formulae can also be called changing the subject. the subject is the variable that you want to find out, or get on its own on one side of the formula. the method for changing the subject is the same as the method used for solving linear equations. step 1. remove any fractions or brackets.

In a formula where the target subject appears twice, it may be necessary to factorise at some point in the process. example make \(y\) the subject of the formula \(y – 2t = p – ny\).
