You can put this solution on YOUR website! What the question is asking you to do is to solve for x. This means that you will need to get x on one side of the equation and everything else on the other side.
.
Notice that within the parentheses you have the quantity x - 1. This entire quantity is multiplied by y.
.
Suppose that you begin by dividing both sides of the equation by y to get rid of the y on the left side. When you do this division you get:
.
.
Now get rid of the -1 on the left side by adding +1 to both sides and you have the answer of:
.
.
You could also have begun the problem by multiplying out the left side ... multiplying y times (x-1). If you do that, the equation becomes:
.
.
Next get rid of the -y term on the left side by adding +y to both sides. The result is:
.
.
Now get rid of the y on the left side by dividing both sides by y to get:
.
.
Simplify the right by dividing both terms in the numerator by y:
.
.
And finally, recognize that . Substitute this equivalent value into the right side of the equation and you have:
.
.
And this is the same answer that we got the first time. It just took a little more work.
.
Hope this helps you to understand the problem better, Kevin.
