Hi there! :)

Answer:

x=7

*The answer must have a positive sign.*

Step-by-step explanation:

<h2>Lesson: Addition/Subtraction/Multiplication/and Division property of equality</h2>

First, you switch sides of an equation.

$x+5=12$

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

$x+5-5=12-5$

You subtract by the numbers from left to right.

$12-5=7$

Final answer is x=7

I hope this helps you!

Have a nice day! :)
