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
 
        
             
        
        
        
Answer:
2. f(-7)= -3(-7)-2
      21-2
       =19
10. h(1)= | 1-7(1) |
      |-6|
      =6
11. h(-7) =|1-7(-7)|
     |1-49|
      |-48|
      =48
12. [23-h(9) =|1-7(-9)|]
       h(9) =|1-7(9)|
       |-62|
          23-62
               =39
