1. Problem: Solve the following system:
            x + y = 11
            3x - y = 5
            
  Solution: Solve the first equation for y
            (you could solve for x - it
            doesn't matter).
            
            y = 11 - x
            
            Now, substitute 11 - x for y
            in the second equation. This gives
            the equation one variable, which
            earlier algebra work has taught
            you how to do.
            
            3x - (11 - x) = 5
            3x - 11 + x = 5
            4x = 16
            x = 4
            
            Now, substitute 4 for x in
            either equation and solve for y.
            (We use the first equation below.)
            
            4 + y = 11
            y = 7
            
            The solution is the ordered pair, 
            (4, 7).

$$\frac {1} {3y} - \frac {2} {4x}  = \frac {4x} {12xy} - \frac {6y} {12xy} = \frac {4x - 6y} {12xy}  $$

You're great! Thank you!

Actually it simplifies to:  

$$\frac {2(2x- 3)} {2(6xy)} = \frac {2x-3} {6xy} $$

Is there be a missing y following the 3?

anonymous · Answer

Hmmm, yeah, forgot the y
