X = 62

Explanation:

You have some value (X), and 29 is being removed from that value. The resulting number is 33. Another way to ask it is, "If I have some number and I take away 29 from it, how can I get 33?" It's actually not very complicated, even though it may look that way.

The way to solve is it to add the 29 to each side of the equation. Why do this? It's because it'll remove the "- 29" from the "X" side of the equation, allowing you to see in clear detail what the value of X is.

X - 29 = 33
X - 29 (+29) = 33 (+29) [The +29 cancels out the -29]
X = 33 + 29
X = 62

The truth is, you could have added any number you wanted to either side of the equation, but only the addition of 29 will allow you to isolate the X. Any time something is done to one side of the equal sign, it has to be done to the other side.

Take care!
