Solve using elimination.......answers must be in ordered pair form....(this is the last one I am confused on)

4x-9y=6.5
7y-2x=-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

5y = -2.5
y = -0.5

etc
