8x-5y=5
3x-8=-y
What is the solution in an ordered pair?

Question

anonymous · Answer

3x-8=-y rewrite is: 3x+y=8
(-8)*(3x+y) =8 
-24x-8y=-64
(3)*(8x-5y) =5 
24x -15y=15
              -24x-8y=-64
             24x -15y=15
Add.....................................
                  -23y = -49
                       Y = 49/23
Substitution Y = 49/23 solve for x
              8x-5(49/23) =5 
               8x-245/23 =5 
               x = 5+(245/23)             
               X = (360/23):8
               X = 45/23
