Question

2.) Which equation represents the balance scale shown? 3x = 7 X-3 = 7 x/3 = 7 x + 3 = 7

Answer 1

As you can see from the figure,

There are 7 dots on the right side of the scale.

On the left side of the scale, there are 3 dots + x

So, we write these numbers on the left and the right side of the equality sign.

`x+3=7`

Therefore, the equation x + 3 = 7 represents the balance scale shown in the figure.
