Answer:
50,27
Step-by-step explanation:
let the parts be x and y
x+y=77
x=2y-4
substitute
2y-4+y=77
3y=77+4
3y=81
y=81/3=27
x=2×27-4=54-4=50
i'm not sure
straight line and line goes through the origin.
without a graph, you will need to divide y/x to seeing there is a constant rate or a constant number every time you divide.
Answer:3x+5+(21)/x-4
