Question

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

Answer 1

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
