  1. Note 6: Changing the Subject of a Formula Changing the subject of a formula, means rearranging the formula to make some other variable (letter) the subject

  2. Example: Make x the subject of the formula in the following: y = mx + c Put the subject wanted on the LHS mx + c = y Subtract c from both sides mx = y - c Divide both sides by m x = y – c m

  3. Example: Make a the subject of the formula in the following: c2 = a2 + b2 Put the subject wanted on the LHS a2 + b2 = c2 Subtract b2 from both sides a2 = c2 – b2 Take the square root of both sides a =
