Answer: (11, 5), (-1, 1)



Solution:



If ( ,5)  = (x, 5) and (-1, ) = (-1, y) then:


for (,5):   
Rewrite x - 3y=-4 as  x -3 (5) = -4
Solve for x: 
x-3(5)= -4
x-15 = -4
x=-4 + 15
x= 11


for (-1,y)

Rewrite x - 3y = -4 as -1- 3y = -4
Solve for y:
-1-3y=-4
-3y= -4+ 1
-3y =-3
y= 1
