Answer:

There is no question stated here so I will improvise.

Step-by-step explanation:   Time Stamp ( 6  9  10  16)

5x+2y=9

5x+10y=75     substract these two equations

0x - 8y = -66

 -8y  = -66

    y  =  -66/-8

    y  =  8.25

5x+2y=9

5x+2(8.25)=9

 5x  = 9 - 16.5

   x  =  -7.5 / 5

   x  = -1.5
