Solving Literal Equations

Literal Equations: an equation with _________________or more variables is called
a literal equation. To rewrite a literal equation, solve for one variable in terms
of the other variable(s).

Example 1: Rewrite a literal equation

a) Solve for y: 3y + 4x=9

b) Solve for x: y=3x+5xz

Example 2: Rewriting and Using Formulas for
Area

a)

S=2lw+2lh+2wh. Solve for (l)

b)

Are of a triangle: A=1/2bh, solve for h.

Example 3: Converting Temperature

a)

C=5/9(F-32), solve for F.

b)

F=9/5C+32, solve for C.

Multiple Choice

Solve for y: $$y-3x=13$$

• $$y=3x+13$$

• $$y=-3x+13$$

• $$y=3x-13$$

• $$y=-3x-13$$
