Solve using elimination.......answers must be in ordered pair form....(this is the last one I am confused on)
4x9y=6.5
7y2x=4.5

the simplest one of your three
did you notice that the order of x and y is backwards in the second?
leave the first alone, multiply the second by 2 and rearrange
4x  9y = 6.5
4x + 14y = 9
add them
5y = 2.5
y = 0.5
etc
