Answer:
There is NO solution
Step-by-step explanation:
Considering 'y' be the number
Considering x be the smaller number
As 'y' is equal to twice a smaller number plus 3.
so

also
y is equal to twice the sum of the smaller number and 1.

so the system of equations become


solving







Therefore, there is NO solution.
Answer: 48x/64
Work (assuming ^ is multiplication):

12x ^ 4x = 48x
4 ^ 16 = 64
Lines b and c
they both go up 2 and over 1 (rise over run is slope)
