Literal equations are equations with more than one variable. Usually, we need to solve the literal equation for one of the variables. This involves moving all the other variables to the other side of the equal sign.

The following diagrams show how to find the vertex of a quadratic function and use that to convert from the general form to the vertex form. Scroll down the page for more examples and solutions for quadratic equations.

**Solving 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. We will need all the methods from solving multi-step equations.

Examples:

Solve for x: 3x = 17

Solve for b: ab = 5

Solve for r: d = rt

Solve for y: x + 2y = 9

Solve for k: m/k = x

Solve for f: (f + 4)/h = 6

**Solving Literal Equations**

Examples on how to solve the literal equations

Examples:

Solve for x: 3x - 7y = 21

Solve for w: P = 2l + 2w

Solve for h: V = 1/3 s^{2} h

**Solving Literal Equations **

Solving for one variable in a formula.

Examples:

Solve for t: d = rt

Solve for r: I = Prt

Solve for w: 2w + 2h + l = p

Solve for r: sr + tr = u

Solve for m: mn = p - mr

**Solving Literal Equations**

Example 1:

Solve b for the following equations.

2b = 8

ab = c

5 + b = 9

a + b = c

2b + 1 = 13

ab + c = d

Example 2:

Solve for c.

4abc = 32

Solve for B.

A = B + C + D
