Develop Understanding
Today's Learning Goal: (G7, U6, L9)
Generalize (orally) that doing the same thing to each side of an equation generates an equivalent equation.
Solve equations of the form px + q = r or p(x +q ) = r that involve negative numbers, and explain (orally and in writing) the solution method.
Today's Materials:
Laptop
Laptop charger
Pen/Pencil/Paper/Expo Marker (optional)

Explain how you know that each equation has the same solution as the previous equation.
With a partner start with
Do the same thing to each side at least three times to create an equation that has the same solution as the starting equation.
Write the equation you ended up with on a slip of paper, and trade equations with your partner.
See if you can figure out what steps they used to transform into their equation. When you think you know, check with them to see if you are right.

What are some important things to keep in mind when working with negative numbers?


-3x + 7 = 1
25x + (-11) = -86
