What would be the first step to solving the following equation?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

Solve the equation. (white is positive and the rectangle is the variable)

• x=10

• x=-4

• x=-10

• x=4

Which equation matches the picture above? ( circles = 1 and triangles = t)

• t = 3

• t + 4 = 7

• 1 + 4 = 7

• 4t + 1 = 7

Which equation matches this model?

• 7x + 3 = 23

• 2x + 4= 10
