  y + 2x = 9
help!!!

add them together :       3y + y -2x +2x =20 
                                      4y =20               because 2x-2x = 0
     divide both sides by 4 to get your y value :   y =5  

plug your y-value into one of the equations:     i'm plugging it into the second equation...
                                     y+2x = 9
                                     5 +2x =9
                                      -5        -5
                                      2x = 4 

divide both sides by 2 to get your x value...

                    x = 2 

so...       y=5 and x=2
