Question

The hanger image below represents a balanced equation,

6
21
Find the value of d that makes the equation true.
MY
d=

Answer 1

d=15

Explanation:

6+d=21

so that means d=15

6+15=21

hope this helped! :)

Answer 2

The value of d that balances the equation is d=15

Explanation:

Equations

We are given an image with a hanger that represents a balanced equation.

If the equation is balanced, then the 'weights' of each side should be equal.

On the right side, there is 21 and on the left side, there are 6 and d.

Adding both, we have 6+d on the left side.

Equating both sides:

6 + d = 21

To find d, we subtract 6 on both sides:

d = 21 - 6

d = 15

The value of d that balances the equation is d=15
