Question

23-х=3 х=23-3 х=20 23-20=3 3=3

Answer 1

Правильно все. не поняла где здесь вопрос?

Answer 2

That's correct!

You started with the equation 23 - x = 3 and wanted to find the value of x that makes the equation true.

You subtracted 3 from both sides of the equation to isolate the variable x on one side, getting:

23 - x - 3 = 0

Then you simplified the left side of the equation to get:

20 - x = 0

Finally, you added x to both sides of the equation to isolate x by itself, getting:

20 = x

You checked your answer by plugging x = 20 back into the original equation:

23 - 20 = 3

Simplifying the left side, you got:

3 = 3

Since this is a true statement, your answer is correct. Well done!
