Make n and l subject of the formula

Step-by-step explanation:

To Make n  subject  of the formula

Step 1

: Cross multiply

Step 2 :

Use n to open the bracket

Step 3 :

Divide both sides by a +l to make n on one side of the equation

Step 4 :

Evaluate n+n = 2n

Divide both sides of the equation by 2

To make l the subject of the formula ,

Step 1 : cross multiply

Step 2 :

Use n to open the bracket

Step 3 :

Move na to the other side of the equation to isolate l

Step 4 : Divide both sides of the equation by n

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
