I am able to us the balance method to solve equations.

Manipulating equations

What is an equation?

How can we manipulate equations? 

We use the balance method.

Solve for x, show your work:

2x=−20

Solve for x, show your work:

3x−2=19

Solve for x, show your work:

−2=5x+23

The next step

Consider the equation

We've just solved

How can we turn that new situation into the known situation?

−2+x=6x+23

−2=5x+23

Solve for x, show your work:

2x+3=−2x+25

Go, go, go!
