how to solve a formula for a specified variable. If you need to put a formula in a spreadsheet it is not unusual to have to solve it for a specific variable first. For example solve x 1 2 x solves the equation x 1 2 for x.
To solve a formula for a different variable you use the same process as you would for a regular equation. Choose a variable to represent it. Write the appropriate formula.
Solve for r d rt 2.
If it is multiplied or divided you do the inverse operation. The solve for variable calculator identifies the variables then add or subtract variables on one side and add or subtract the whole numbers on other side. This process is also called solving a literal equation. If you do not specify var the symvar function determines the variable to solve for.
