There is no real root present.
Answer:
The answer is 2 6/8
Step-by-step explanation:
Answer:
Let's just call the number x. 3/8ths of x and 1 more equals 11.
As an equation, this basically means

We want to use elimination to solve
y = 0 (1)
x + y = 40 (2)
Multiply (1) by -1 to eliminate y.
-y = 0 (3)
Add (2) and (3).
x + y + (-y) = 40 + 0
x = 40
Answer: Multiply by -1.
