Answer 1

Hi there!

Answer:

Subtraction property of equality.

x=4

The answer must have a positive sign.*

Explanation:

Subtraction property of equality

a-c=b-c

First, you switch sides of an equation.

`x+5=9`

Then, you subtract by 5 from both sides of an equation.

`x+5-5=9-5`

Finally, you can also subtract by the numbers.

`9-5=4`

Answer:
`x=4`

Hope this helps!

Thanks!
