Modeling and Solving Algebraic Equations

What equation is modeled?  Solve the equation.

• x -6 = 13     x = 19
• x + 6 = 13    x = 7
• x + 6 = 13    x = 8
• x - 6 = 13   x = 7

What would be the first step to solving the equation being modeled? (green=x red = -1 blue = 1)

• Add 4 red tiles or -4 to both sides

• Add 4 blue tiles or 4 to both sides

• Add 10 red tiles or -10 to both sides

• Add 10 blue tiles or 10 to both sides
