Find the solution of the system of equations.
- 7x – 4y = -44
7x - 3y = 16

{x,y} = {5,8}

Step-by-step explanation:

 [1]           7x-3y+5=16

 [2]           4y=3x+17

  [1]    7x - 3y = 11

  [2]    -3x + 4y = 17

// Solve equation [2] for the variable  y  

 [2]    4y = 3x + 17

 [2]    y = 3x/4 + 17/4

// Plug this in for variable  y  in equation [1]

  [1]    7x - 3•(3x/4+17/4) = 11

  [1]    19x/4 = 95/4

  [1]    19x = 95

// Solve equation [1] for the variable  x  

  [1]    19x = 95  

  [1]    x = 5  

// By now we know this much :

   x = 5

   y = 3x/4+17/4

// Use the  x  value to solve for  y  

   y = (3/4)(5)+17/4 = 8

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
