Linear Equations in Disguise!
January 31, 2017
I can rewrite and solve equations
that are not obviously linear equations
using properties of equality
Warm-Up: Solve each equation.
-5(x + 2) = 3x + 6
2x + 3x = 2x - 12

Concept Development.
x 6
=
5 12
What do we call this kind of problem?
How do we solve it?
4
Concept Development.
x 6
=
5 12
A proportion is really a linear equation in disguise!
5 * 6 = 12 * x
30 = 12x
5
Parenthesis...
We can add them without changing what
the expression/equation is saying...
5 * 6 = 12 * x
