Monday we talked about 3 steps to solve an equation.

Steps to Solving Equations:
1. Use the opposite operation to ISOLATE the variable to one side of the equation
2. SOLVE for the Variable3. CHECK the answer to the equation by
substituting the number in for the variable

Today we will use an Equation Mat and Integer Chips to model solving an equation.

Equation Mat Directions… Yellow=positive 1 Red= negative 1 Use the chips for our numbers. If the equation is x+3=5…on your mat you should
have
x + =
Then, use your red chips to solve the equation. The red and yellow chips cancel out. We are left with 2 yellow chips, so x=2.

X + 5 = 13 - 5 - 5_________
Let’s look at the left side. What will you get when you combine + 5 and -5 ?
That’s right, zero. And zero is nothing, so let’s cancel out + 5 and -5.
Click on the pen when you are ready.
Click on +5 or -5 to cancel them.
Now to the hard part.

Let p represent the profit in 2002 (in millions of dollars).
This year’s profit300
is =
300 = 100 + p–100 –100
