Solve One Step Equations with Pan Balance Equations

Use the pan balance to model and solve the equation.

8 + 7 = 5 + x

Use the pan balance to model and solve the equation.

2 + z = 4 + 10

Which value of p makes the equation true? 5 + p + 7 = 5 + 6 + 5

• 4

• 6

• 8

How would you balance the pan balance?

• Add 4 cubes to the left side of the balance.

• Take away 4 cubes from the right side of the balance.

• Move 4 cubes from the right side of the balance to the left side of the balance.

• Move 8 cubes from the right side of the balance to the left side of the balance.

The equation 10 = x - 3 is represented by the model shown.

Which represents the solution to this equation?​ (a)  

• x = 13

• x = 3

• x = 7

• x = -7
