Question

this scale was balanced find the number to add that make the scale become balanced again then ccomplete the equation to make it true

Answer 1

To balance the scale, add 16 to the left side of the equation. The balanced equation is 12 + 16 = 2 + 7 + 3 + 16, resulting in 28 = 28.

To balance the scale, find the number to add on the left side of the equation. The equation is currently:

`\[ 12 + \_\_ = 2 + 7 + 3 + 16 \]`

Combine the numbers on the right side:

`\[ 12 + \_\_ = 28 \]`

Now, subtract 12 from both sides to find the value of the blank:

`\[ \_\_ = 28 - 12 \]`

`\[ \_\_ = 16 \]`

Therefore, adding 16 to the left side of the equation will balance the scale:

12 + 16 = 2 + 7 + 3 + 16

The balanced equation is:

28 = 28

The probable question may be:

This scale was balanced. Find the number to add that makes the scale become balanced again. Then complete the equation to make it true.

12 + __ = 2+7+3+16
