(x)/(x)+1-2=(3)/(x)-3
Find the LCD (least common denominator) of (x)/(x)+1-2+(3)/(x)-3.
Least common denominator: x
Multiply each term in the equation by x in order to remove all the denominators from the equation.
(x)/(x)*x+1*x-2*x=(3)/(x)*x-3*x
Simplify the left-hand side of the equation by canceling the common terms.
0=(3)/(x)*x-3*x
Simplify the right-hand side of the equation by simplifying each term.
0=-3x+3
Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
-3x+3=0
Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.
-3x=-3
Divide each term in the equation by -3.
-(3x)/(-3)=-(3)/(-3)
Simplify the left-hand side of the equation by canceling the common terms.
x=-(3)/(-3)
Simplify the right-hand side of the equation by simplifying each term.
Answer: x=1

*************************************************
x%2F%28x+%2B+1%29+-+2+=+3%2F%28x+-+3%29, with system%28x+%3C%3E+-+1%2C++x+%3C%3E+3%29
x(x - 3) - 2(x + 1)(x - 3) = 3(x + 1) ---- Multiplying by LCD, (x + 1)(x - 3)
  x%5E2++-++3x++-++2%28x%5E2++-++2x++-++3%29+=+3x+%2B+3
       x%5E2++-++3x++-++2x%5E2+%2B+4x+%2B+6+=+3x+%2B+3
       x%5E2+-+2x%5E2+-+3x+%2B+4x+%2B+6+=+3x+%2B+3
                       -+x%5E2+%2B+x+%2B+6+=+3x+%2B+3
       0+=+x%5E2+%2B+3x+-+x+%2B+3+-+6+=+0
                       x%5E2+%2B+2x+-+3+=+0
                 (x - 1)(x + 3) = 0 --- Factorizing the trinomial
 x - 1 = 0      OR    x + 3 = 0 --- Equating each binomial to 0
       x = 1      OR           x =  -  3 
 
Neither of the 2 solutions is - 1 or 3, so BOTH are VALID!
