Answer: 3/8

Explanation:

Given:


B-(-(1)/(8) )+c

replace variables with their given values: b = 2 and C = 7/4


2-(-(1)/(8))+(-7)/(4)

to make subtracting and addition easier, make each number has the same common denominator.


(16)/(8) -(-(1)/(8))+((-14)/(8))

Finally, solve equation.

***remember that subtracting a negative is the same as just adding and adding by a negative is the same as simply subtracting.


(16)/(8) -(-(1)/(8))+((-14)/(8))=(16)/(8) +(1)/(8)-(14)/(8)

= 3/8
