Hello There:
I'm not totally sure what the equation is because of the placement of the parentheses, so I'm going to guess that it's:
5/x + 9/(9*x) = 3
Clear the fractions by multiplying both sides of the equation by 9*x (the common denominator).
(9*x)*(5/x) + (9*x)*(9/[9*x]) = (9*x)*3
45 + 9 = 27*x
This simplifies to:
27*x = 54
Solve for x by dividing both sides by 27.
(27*x)/27 = 54/27
x = 2
Let's check our answer by substituting our result for x in the original equation.
5/2 + 9/(9*2) = 3
5/2 + 1/2 = 3
6/2 = 3
3 = 3
It checks out.
