Answer:
Given,
The total distance covered = 4 km,
Since, initially he would be in rest,
So, his starting point would be 0.
Now, his first break =
km,
Second break =
km,
Also, we can write,

Drawing number line:
Step 1: Draw a line.
Step 2: Make 12 marks in same distance.
Step 3: Starts from 0, then 1/3, 2/3, 3/3 and so on.
Thus, we can show Wayne's bike on a number line as below.

Answer:
Step-by-step explanation:
Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x
-12x+12x+72=-24
The xs cancel, which leaves you with 72=-24
Since 72 cannot equal -24 there is no answer to this system of equations
