Solving Literal Equations and Formulas

Remember, to solve linear equations we “get rid of”
1._________________________________________________________________
2._________________________________________________________________
3._________________________________________________________________
4._________________________________________________________________
5._________________________________________________________________

Use these procedures to evaluate the following formulas and to solve for an indicated variable:
1. Use the formula d = rt, where d is distance, r is rate of speed, t is time, to (a) find the distance
traveled by a car that travels 5 hours at 60 mph. (b) to find the rate of speed of a car that
travels 450 miles in 9 hours first solve for r.

2. The formula for the area of a triangle is A = (1/2) bh where b is the length of the base of the

triangle and h is the height or altitude of the triangle.
Use the formula to find the base of a triangle that has an area of 60 square meters and
a height of 7 meters by first solving for b.

When working with scientific formulas it is often helpful to solve the formula itself for a given
variable – rather than substitute values. In each of the following equations, solve the formula for
the indicated variable, “getting rid of “ variables rather than numbers.
