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

A local art studio offers a new session of drawing classes every 12 days. A competing art studio offers a new session of drawing
Artist 52 [7]
To solve this we are going to find the least common multiple of 8 and 12.
Remember that the least common multiple (LCM) of tow or more numbers is the smallest positive number that is multiple of those two or more numbers. 
To find our LCM we are going to list the multiples of 8 and 12, and then, we are going to select the first common number in those lists:

Multiples of 8: 8,16,24,32,40,....
Multiples of 12: 12,24,36,48,...

Notice that the first common value between the two list is 24, and that is precisely the number of days it will take for drawing sessions to coincide.

We can conclude that after 24 days both<span> art studios will start a new drawing session on the same day.</span>
