2. x + y = 82
    x - y = 24
  ---------------add
    2x = 106
      x = 53
 
   x + y = 82
   53 + y = 82
   y = 82 - 53
   y = 29

   solution is : (53,29)
=======================
3. y = 2x
    y = 4x + 6
    
    2x = 4x + 6
    2x - 4x = 6
    -2x = 6
     x = -3

    y = 2x
    y = 2(-3)
    y = -6

    solution is (-3,-6)
========================
4. 5x + 8y = -29
    7x - 2y = -67...multiply by 4
   ----------------
    5x + 8y = -29
   28x - 8y = - 268 ..result of multiplying by 4
  -----------------add
   33x = - 297
      x = - 9

   5x + 8y = -29
   5(-9) + 8y = -29
    -45 + 8y = -29
   8y = -29 + 45
   8y = 16
   y = 2

   solution is : (-9,2)
=======================
5. y = -4x + 6
    y = -5x - 4

    -4x + 6 = -5x - 4
    -4x + 5x = -4 - 6
     x = -10

    y = -4x + 6
    y = -4(-10) + 6
    y = 40 + 6
    y = 46

   solution is (-10,46)
=========================
6. H(m) = 2m + 12
    H(m) = 3m + 10
=========================
7. -8x + 4y > -52
    4y > 8x - 52
     y > 2x - 13 <==
=========================
8. 3x - y = 28
    3x + y = 14
   ---------------add
    6x = 42
     x = 7

   3x - y = 28
   3(7) - y = 28
   21 - y = 28
   -y = 28 - 21
   -y = 7
    y = -7

solution is (7,-7)
=====================
10. 5x - 5y > 70
      -5y > -5x + 70
       y < x - 14 <==
=====================
11. sorry...dont know
=====================
12. y = 4x + 4
      y = -3x - 3

     4x + 4 = -3x - 3
     4x + 3x = -3 - 4
     7x = -7
     x = -1

     y = 4x + 4
     y = 4(-1) + 4
     y = 0

solution is (-1,0)
=======================
13. -12x - 2y > - 42
       -2y > 12x - 42
        y < -6x + 21 <==
=======================
14. -5x + 2y = 9
       3x + 5y = 7

solution is (-1,2)
========================
15. 3x + 6y = -2
     15x + 30y = -10....divide by 5 to reduce = 3x + 6y = -2
     is the same line....infinite solutions
========================
1. (the graph).....y < = 3x - 4....3rd one
========================
9. (2nd graph)....y < = -3x + 4....last one
