i am checking an answer for this one but i can get confused

anonymous · Answer

can you help me out with this one
 x+2y=9
x+y=28

anonymous · Answer

your object is to remove one of the variables.  so you have to find the simpliest way to do that.  

here i would multiply 2nd by negative 1

x +2y = 9
-x -y = -28

     y = -19

plug that back into one either one 

x + 2y = 9

x + 2(-19) =9
x -38 = 9
x =9 +38
x =47
