Question 93582

2/3x+2y=18    Multiply 2 times the upper equation
 -2x+2y=-6  
----------
8/3x   =24    Subtract the lower equation from the upper
      x=9     Multply both sides times 3/8
(-2*9)+2y=-6  Substitute 9 for x in either of the 2 equations
       2y=12  Add 18 to both sides
        y=6   Divide both sides by 2.
