86 Naira; divide 1075 by 12.5 (hopefully this is correct!)
if you make a graph and add the coordinates on the graph you can use that find out how it creates a ratio of 1:2
121 is a Rational number .
-2x-4y = 2
-2x-4y+4y = 2+4y
-2x=4y+2
Divided by 2:
-2x/-2 = 4y +2/ -2
Answer: x=-2y-1
3x +4y =8
3x + 4y = -4y = 8+-4y
3x= -4y +8
Divided by 3
3x/3 = -4y + 8/3
x=-4/3y + 8/3
