Solving Formulas for Different Variables. Often it is useful to solve a formula for a different variable, for example, the formula for speed is. To solve a formula for a different variable, you use the same process as you would for a regular equation. If a variable is added, you add the opposite to both sides. If it is multiplied or divided, you do the inverse operation. The only difference is that you are using variables instead of numbers. For example, let's solve I=Prt (the interest formula) for t. We could move both in one step, but we'll do them one at a time to be extra clear. Let's move the P first. The P is being multiplied by the t, so we have to do the reverse: divide both sides by P. The P's on the right hand side will cancel each other out and we are left with: We still have to move the r. It is also being multiplied, so we will divide both side by r. We can reverse the sides of the equation if we want. We now have the equation solved for t instead of I. Let's try one more: Let's solve the formula for the area of a triangle f for b. Solving for a Specific Variable Solve the equation for the indicated variable. Solving formulas for a specific variable PDF solving formulas for a variable worksheet PDF solving equations and formulas worksheet PDF solving equations and formulas calculator PDF. Let's move the h first. The h is being multiplied by the b, so we have to do the reverse: divide both sides by h. The h's on the right hand side will cancel each other out and we are left with. We still have to move the . In these lessons, we will learn how to solve a formula for a variable. It is also called solving literal equations. Let us review the steps as follows when we need to solve for a variable in a formula. It is also being multiplied, so we will divide both side by . Remember that to divide by a fraction, you flip it and multiply, so we will flip , which gives us 2. We will now multiply both sides by 2. We can reverse the sides of the equation if we want.
