What is the value of the expression when a = 6, b = 4,and c = 8?
2a/3b−c
a. 1
b. 3
c. 8
d. 12

The answer is: [B]: 3.

Let us assume that the problem is meant to be written as:

  2a / (3b - c) ;

Explanation:

we are given the values for "a", "b", "c" ; and we are asked to solve the problem when the given values: 
      a = 6, b = 4; and c = 8 .

Note:

We have a "numerator" , " 2a " ; and a "denominator" , (3b - c).

Let us start by finding the numerator: 

Numerator: 2a = 2*a = 2 * 6 = 12.

Denominator: 3b - c  = (3*4) - 8 = 12 - 8 = 4

To solve: Numerator ÷ Denominator = 12 ÷ 4 = 3.

The answer is: [B]: 3.
