1. Modeling and Solving 2-
operation Equations
You can use algebra tiles to solve
equations.
= variable =1
= -1

2. 2y + 4 = 10
Should I put things into groups first or should I try
to simplify the scales by removing like items from
each side?

3. 2y + 2y = 10
4 =6
Remove the four squares from each side to simplify
the equation!

4. 2y = 6; separate your variables
y=3
and split up the ones so that
each variable has the same
amount

5. Model and solve.
4x + 2 = -10

6. Solve – show your steps!
4x - 10 = 34 -3n + 15 = 60
