Answer:
the value of a is 4 ÷ 7
Explanation:
The computation of the value of a is shown below:
Given that the following equation
|7|x| - 4 = a
Based on the above equation
As we can see that the modulus is applied
So after removing the modulus, it would be
7x - 4 = a
7x = 4
x = 4 ÷ 7
Hence, the value of a is 4 ÷ 7
