Change subject of a formula. to change the subject of a formula is to rewrite the formula so a single unknown variable is equal to the rest of it. we can use this technique to rearrange equations and solve equations. step by step guide: rearranging equations. step by step guide: solving equations. to rearrange formulae, we need to use inverse. This section covers using and rearranging formulae and substituting numerical values in formulae. to rearrange formulae you should remember the following rules: begin by removing any square roots on both sides of the equation. then multiply out any brackets. multiply out all terms by the denominator to remove any fractions. Multiply each side of the equation by the denominator. show step. expand the bracket on the left hand side of the equation. this will help us get all terms with x onto one side of the equation. show step. if we factorise the left side of the equation we will be left with only one of the variable x. show step.

Line 1: we want to get r all by itself on one side of the equation, so first we must remove the brackets by multiplying each term inside the brackets by p. the equation becomes a equals p plus p r t. line 2: remove p on the right side of the equation by subtracting p from both sides so the equation becomes a minus p equals p minus p plus p r t. The area of a rectangle is a equals l times w where a is the area, l is the length and w is the width of the rectangle. we say that a is the subject of the formula, let’s say we want to find the width, w, so we use the rule division undoes multiplication by dividing both sides by l. so let’s do that. we divide the left hand side by l, which.
