Model One-Step Equation

Solve for x

• x = 4

• x = 1

• 2x = 4

• x = 2

What equation is modeled? Solve the equation.

• x -6 = 13

• x + 6 = 13

• x + 6 = 13

• x - 6 = 13

Write the equation for the model. (white square=1 rectangle=x red square = -1)

• 7=x+3

• 7=x+(-3)

• 7=-x+3

• -7=x-3

If the triangle represents the variable and each circle equals one, is this model and equation in the image correct?

• Yes

• No, there needs to be 7 circles on the right side of the equal sign.

• No, there needs to be 4 circles on the right side of the equal sign.

• No, there needs to be a minus sign in the equation.
