Answer:

x=1.875   y=-0.875

Step-by-step explanation:

10x-3y=3                     10x-3y=3

3(2x+y)=(9)3                +<u>6x+3y=27</u>

                               1/16(16x)=(30)1/16  = x=1.875

   10x-3y=3                  10x-3y=3

 -5(2x+y)=(9)-5           -<u>10x-5y=4  </u>                        

                                    1/-8(-8y)=(7)1/-8 = y=-0.875
