yes you can
do 43+57 which is 100 then do 100+68 which is 168 the answer is 168
Subtract 3x from each side: 5 = x - 10; Add 10 to each side: 15 = x; Job done.
40 + X = 25 subtract 40 from each side
example: 4x+5=13 First step: you must subtract 5 on each side. 4x=8 Second step: you must divide must side by four then it equals x=2

4x9x50=200x9=1800
You kind of need to know the problem?
So that anyone looking at your answer is able to work out each step you've taken to get to your final result. It also means if you make a mistake, you can easily find where you have made the mistake
This is called the Scientific method. It includes these steps :Use your experience: Consider the problem and try to make sense of it. Look for previous explanations. If this is a new problem to you, then move to step 2.Form a conjecture: When nothing else is yet known, try to state an explanation (to another experimenter or to your notes).Deduce a prediction from that explanation: If you assume a conjecture is true, what consequences follow?Test: Look for the opposite of each consequence which would then disprove the conjecture. It is a logical error to seek the predicted results (3) directly, as proof of the conjecture. This error is called affirming the consequent.

The word "conjecture" can be taken a number of ways. If the "conjecture" involves an inference based on false or defective information, you need only show convincing or conclusive evidence that the information is false or faulty. If the "conjecture" is the result of surmise or guessing, then it is nothing more than a guess itself, and, therefore, has no basis in fact or logic. If the "conjecture" is an unproven mathematical hypothesis, you will need to disprove its validity from its basis. Start with the basic crux of the problem and work step by step until you disprove (or prove) the hypothesis to be untrue (or true). Make sure you have good arguments and sound mathematics.

An example of a two step equation that equals 2 is 4 + 2x = 2. In this equation, x = -1.
