x = 12
Step-by-step explanation:
To solve this and show your work, you have to start of with the equation (3x - 6) = 30.
You then have to add 6 to both sides like this:
So then the 6 is cancelled out, and you are left with
3x = 36.
Now you just have to divide both sides by 3 like this:

Answer:
Step-by-step explanation:
Given
Let the number be x
So:
Required
Using trial and improvement, find x
This implies that we keep guessing the values of x until we get a value that match the equation.
Let
So, we have:
Take the square root of 625
Let
So, we have:
Take the square root of 729
At this point, we can conclude that x is approximately 729 because
So:
