Value of the given expression b- 2a-c for variables a = -7 , b = 3 and c = -7 is equals to 24.
What is evaluate?
"Evaluate is defined as an algebraic expression for which we substitute the values of the given variables to get the value of the expression."
According to the question,
Given values of the variables,
a= -7
b = 3
c = -7
Substitute the variables values to evaluate expression we get,
b - 2a - c
= 3 - 2(-7) - (-7)
= 3+ 14 + 7
= 24
Hence, value of the given expression b- 2a-c for variables a = -7 , b = 3 and c = -7 is equals to 24.
