=
The common denominator would be 3x, multiply both sides by 3x
(With single fractions on each side, you can cross multiply and do the same thing)
3x*
= 3x*
cancel the denominators
3(-3) = x*x
-9 = x^2
x =
x =
square root of a negative presents a problem, we have to use i, the square root of -1
x = i*
x = 3i

+
This is not an equation, we can only combine it into a single fraction
To add we have to have a common denominator, we can make this by multiplying
the 2nd denominator by -1, this changes the signs inside the brackets
+
divide the -1 into 3 and we have;
