The solution to your problem is m>-2
Answer:
4x-12y=9
Step-by-step explanation:
y=1/3 x + 3/4
1/3 x-y=3/4
(x-3y)/3=3/4
4(x-3y)=3×3
4x-12y=9
It depends what your trying to get close to. If your trying to get close to a number that is easier to work with 1 4/8 is good because its the same as 11/2 but the closest whole number is 1.
