#### Transcript of Copy of Literal Equations

**Literal **

Equations

Literal equations are also formulas...

Solving for a single variable

Equations with only variables..

In this lesson you will rewrite

and use literal equations

**Let's Review**

What are literal equations?

It will look like this:

Solve the equation 10x + 5y= 80 for y

Looks something like this:

ax + b = c solve for x

Area of a triangle: A= 1/2bh

distance travled: d= rt

Temperature: C= 5/9(F-32)

hint: literal equations have more than one variable

All this means is to get y by itself...

For example:

10x + 5y = 80

-10x -10x

5y = 80 - 10x

y = 16 - 2x

Or this...

m-d/e =g solve for d

Can you solve for t?

d= rt

What does it mean to solve for a variable?

Classwork

ax + b = c

-b -b

ax = c - b

x = (c-b)/a

m-d/e = g

m-d = eg

-m -m

-d = eg - m

d = m - eg
