The expression when a=−15 and b=−5 is -3/5
To evaluate the expression, we need to know that algebraic expressions are defined as expressions that are composed of terms, constants, factors and coefficients.
From the information given, we have that the expression is given as
b + 14/a
Where the values are a= -15 and b = -5
substitute the values, we have;
(-5) + 14/-15
expand the bracket, we have;
-5 + 14/-15
9/-15
divide the values
-3/5
