Question

What do the three red tiles in the model of the equation below represent?

Answer 1

Left side:

x + x + 1 + 1 + 1 = 2x +3

Right side:

(-x) + (- x) + (- x) = -3x

Answer:

-3x

Answer 2

the three red tiles in the model represents -3x

Explanation:

From the given diagram, the three red tiles have -x, -x and -x

To find what 3 red tiles represents , we need to add all the three red tiles

Red tiles represents -x + -x + -x

Combine all the terms to add it

All terms are like terms. -x means -1x

`-1x+(-1x_+(-1x) = -1x-1x-1x= -3x`

So , the three red tiles in the model represents -3x
