There is no need to rearrange the expression. Think about what it means for this fraction to be equal to 1 (hint: means the numerator and denominator are equal). So, your numerator is 2•2-1=3 hence the expression below is equal to 3 too. Since it's of the form 1+f where f is another fraction, that entire fraction is equal to 2. And then continue in the same manner until you reach the end. You should find that x = 6
