Answer: h(x) = 
<u>Step-by-step explanation:</u>
6x + y = 4x + 11y
<u>      -y </u>    <u>        -y  </u>
6x       = 4x + 10y
<u>-4x   </u>      <u>-4x         </u>
2x       =         10y
<u>÷10    </u>     <u>       ÷10 </u>
 =            y
    =            y
Since "y" represents h(x), then h(x) =

Answer:
when x = -1,  y = -3 
when x = -1,  y = -1
when x = -1,  y = 1
when x = -1,  y = 3
Step-by-step explanation:
x = -1;  plug in y = 2(-1) - 1 = -2 - 1 = -3
x = 0;  plug in y = 2(0) - 1 = 0 - 1 = -1
x = 1;  plug in y = 2(1) - 1 = 2 - 1 = 1
x = 2;  plug in y = 2(2) - 1 = 4 - 1 = 3
