would be great. Please explain in simple terms.
here is a couple problems I am having trouble with,

It helps some times to think of an equation as a scale that has a pan for weights on each side. In your problem #1 the sacle is balanced with a weight of 3/4 n - 6 on one side and 12 on the other.
The task is to move the weights around, always maintaining the balance, and end with one side having only n on it. The balance is maintained if you add the same amount to each side, subtract the same amount from each side, multiply each side by the same amount or divide each side by the same amount. Lets start with problem #1.
The left side has 3/4 n - 6 on it and I want only n on this side, so the first step I would take is to add 6 to each side. This will maintain the balance and eliminate the - 6 from the left side.Thus
Now multiply each side by 4 to get
You should check your answer by calculating 3/4 n - 6 when n is 24 to see that you get 12.
Problem #2 is similar with one extra complication. In this problem you have 1 3/4 as the coefficient of x. Before you start through the steps above you should write 1 3/4 as a common fraction rather than a mixed fraction. That is write 1 3/4 as 7/4. Now go through steps similar to what I did above to get x alone on the left side.Let me know what you find for x.
