Directions: Using the digits 1 to 9 at most one time each, fill in the boxes to create two expressions that are equivalent to one another.

### Hint

What values will make the constants equivalent? What values will make the variable terms equivalent?

### Answer

Here are some possibilities:

1x + 2x + 9 + 3x = 4 + 6x + 5;

1x + 2x + 8 + 4x = 3 + 7x + 5

1x + 2x + 9 + 3x = 4 + 6x + 5;

1x + 2x + 8 + 4x = 3 + 7x + 5

answer 3x+2x+8+4x=1+9x+7

8x+5x+2+4x=4+5x+9

good

Answer: 1x+2x+3+1x=4x+3

5x + 3x + 4 + 1x = 3 + 9x + 1

I changed my answer. 4x + 2x + 8 + 3x = 7 + 9x + 1

3x + 8x + 4+ x = 2 + 12x + 2

3x+1X+8+5x=6+9x+2

answer 5x +3x + 4 + 2x = 3 + 7 + 4x
