Problem #10

What is the value of "x"
x in the equation represented by the tiles?

3
3

5
5

negative 3
−3

negative 1
−1

Answer 1

I don’t have the tile diagram — I only see a list of numbers (3, 3, 5, 5, −3, −1). I need to know which tiles are on the left side of the equation and which are on the right (or you can upload the image).

Can you either
- upload the picture of the tiles, or
- tell me exactly which tiles are on the left and which are on the right (for example: left = 3x and +3; right = 5x and −4),

and I’ll solve for x.

If you meant the common arrangement "left: 3x + 3" and "right: 5x − 4" (i.e. tiles 5 and 5 combine to 5x and −3 and −1 combine to −4), the solution would be:
3x + 3 = 5x − 4
3 = 2x − 4 → 7 = 2x → x = 7/2 = 3.5.

Tell me the left/right grouping and I’ll give the exact answer.
