# Practice Solving Literal Equations

A literal equation is generally a formula for example $$A = \frac{1}{2} bh$$.  We can solve the equation for any of the variables in the problem by using the methods for solving an equation as was shown in the video. In Module LINR 1 Lesson 4, you solved a literal equation when you converted an equation of a line written in Standard Form and solved solved for $$y$$ to convert it to Slope-intercept Form.

Try the following problems:

1. Given the equation $$3x+2y = 8$$, solve for $$y$$.

1. Given the equation: $$A = \dfrac{1}{2} h(b_1+b_2)$$ solve for $$h$$.

1. Given the equation: $$V = \dfrac{1}{3}\pi r^2h$$,  solve for $$h$$.
