After graphing both lines, we're able to tell the solution by looking at the point where the lines cross. In this case, it's at (4, -1). And so that is the solution set.
Answer:
30
Step-by-step explanation:
The equation of the line is x = 4.
a=2d+3
b=3d-12
c=a+b so
c=2d+3+3d-12
c=5d-9
14 and 28 in
Step-by-step explanation
the ratio= 2:1
so thre are 3 parts
42/3 = 14
multiply by 2 and get 28
