**What is a literal equation?**

A literal equation is an equation with more than one variable.

**What does it mean to solve a literal equation?**

To solve a literal equation means to isolate the indicated variable.

**How to Solve Literal Equations?**

Sometimes we need to use methods for solving literal equations to rearrange formulas when we want to find a particular parameter or variable. Solving literal equations is often useful in real life situations, for example we can solve the formula for distance, d = rt, for r to produce an equation for rate.

**How to solve literal equations (equations with more than one variable)?**

1. A = LW, solve for W

2. P = 2L + 2W, solve for L

3. A = 1/2 bh, solve for b

4. A = 2LW + 2WH + 2HL

**Solving Literal Equations Part 1**

Solving for one variable in a formula.

1. d = rt, solve for t

2. I = Prt, solve for r

3. 2w + 2h + l = p, solve for w

4. sr + tr = u, solve for r

5. mn = p - mr, solve for m

**Solving Literal Equations Part 2**

1. T = 3/10(I - 12,000), solve for I

2. V = 4/3πr^{3}, solve for π

3. v = (x - y)/m, solve for m

**Solving Literal Equations for a Variable - Algebra 1**

Examples:

1. 3x - y = 7, solve for y

2. 3a = -6b + 5, solve for b

3. (8a + 2)/c = 4, solve for c

**Literal Equations - Algebra Help**

How to solve for a given variable in a formula by isolating the given variable on one side of the equation? Example:

3mn^{2} - p = q, solve for m

**Solving Literal Equations**
