Substitution for Y+6X-11 and -2X-3Y=-7

y =  5/3 x = 19/9

Step-by-step explanation:

Solve equation [2] for the variable  y  

  [2]    3y = 5  

  [2]    y = 5/3   Plug this in for variable  y  in equation [1]

  [1]    (5/3) - 6x = -11

  [1]     - 6x = -38/3

  [1]     - 18x = -38

Solve equation [1] for the variable  x  

  [1]    18x = 38  

  [1]    x = 19/9  

By now we know this much :

   y = 5/3

   x = 19/9

We are done

b.   e = 7.5h

hope this , lovely!
