</h2>
Step-by-step explanation:
Rewrite the first equation

Now we have the following system of equations

To solve the system of equations multiply the first equation by -1 and add it to the second equation


+

-----------------------------------

Now substitute the value of x in any of the two equations and solve for y






The solution is:

It is 7
2 below the zero, 12 above = 14 steps
middle point is 7
