Question

The model represents an equation. What value of x makes the equation true?

Answer 1

D. x = 3

You can get this by turning these into equations

-3x + 6 = 2x - 9

Then solve. 

Answer 2

Answer:

value of x=3

Step-by-step explanation:

Use the model to find the question and solve for x

-x  -x  -x represents -3x

1  1 1 1 1 1 represents 6

x  and x represents 2x

-1  -1  -1     -1     -1    -1  -1    -1    -1   represents -9

The equation becomes

-3x + 6 = 2x -9

Subtract 2x on both side

-5x +6 = -9

subtract 6 on both sides

-5x= -15

divide by -5

x= 3
