Measure the distance between the two end points, and divide the result by 2. This distance from either end is the midpoint of that line. Alternatively, add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.
Answer:
40. This is so easy yet so dumb. Why is this even a question?
Step-by-step explanation:
Lets write as an equation:
x/4 + 18 = x
to get rid of fraction lets multiply the whole equation by 4:
x + 4*18 = 4x
x + 72 = 4x
3x = 72
x = 72/3
x = 24
that is the solution
