Lesson 29
Solving literal equations

2. A literal equation is an equation with more than one variable.
Use inverse operations to solve for a specific variable.
The solution will be in terms of the other variables.

3. Solving for a variable Solve for y: 2x+3y =10 Subtract 2x -2x -2x
Div by
y = -2x + 10

4. Solving for variables on both sides
Solve for p:
4p + 2a -5 = 6a + p
Eliminate p p p
from one side 3p + 2a -5 = 6a
Subtr 2a a a
3p = 4a
Add
3p = 4a + 5
Div by
p = 4a + 5

5. solve
Solve for r:
3r + 2s -7 = -4s + 4r -8

6. Solving a formula for a variable
C = 5/9 ( F-32)
solve for F
Mult by 9/ C = 5/9(F-32)
9/5 C = F-32
Add /5 C +32 = F
