Name:Period:Date:Topic: Solving Literal Equations

Essential Question: Can equations that appear to be different be equivalent and how can you solve them?

Using the formula Distance: Rate x Time or D=RT, we can solve

the formula for R or T.Given: d = rt solve for r

The formula for area of rectangle is A = lw.

Find the formula for l.

BACK

Given: P = 2l + 2w Solve for w

BACK

3d + 14 = 7e – 4d Solve for d

Solutions to last four slides:

1. d = rt solve for r

2. A = lw solve for l

3. P = 2l + 2w Solve for w

4. 3d + 14 = 7e – 4d Solve for d

Solutions:

1. r =

2. l =

3. w =

4. d = e - 2

1) Solve 2x - 4y = 7 for xTo get x by itself, what is the first step?

1. Add 2x2. Subtract 2x3. Add 4y4. Subtract 4y

Rewriting Literal Equations &

Finding Values:

10x + 5y = 80 Solve for y

Use re-written equation to find y when x = 3 and when x = 6

y + 2x = 5 Solve for y.

Then find the value of y for each value of x: x = - 1 and x = 0
