N/2-2n/16=3/8
it's basic algebra

n/2 - 2n/16 = 3/8 it's basic algebra.

Step 1 :

n/2 = 8n/16 multiply both numerator and denominator by 8.

3/8 = 6/16 multiply both numerator and denominator by 2.

Step 2 : we can add the fractions since now they have the same denominator

8n/16 -2n/16 = 6/16

(8n - 2n -6)/16 = 0

(6n - 6)/16 = 0

6n - 6 = 0

6n = 6

n = 6/6 = 1 This is the n value

Answer n = 1

Hope this helps!

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

answer: the answer is   graph (a)
