Solve the proportion x over x plus 1 equals 4 over x plus 4. What is the value(s) of x?
See a solution process below:
We can write this proportion as:
Next, we can do cross product or cross multiply the equation:
We can now put this in standard form:
Then, the left side of the equation is a difference of squares so we can factor it as:
Now, to find the values of
