that means to replace the variable with it's value, and then do all the mathematical symbols as normal (+-x/)
It means you replace each instance of the given variable with the given value. For instance, you have the following equation: A(A+2A)= B Then someone says to "substitute the value '4' for each instance of 'A'. You'd just replace them, and get: 4 ( 4 + 2(4)) = B
It is called evaluating the equation.
normally when people say "which of the following" there are actually choices following it below...
Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
the independent variable
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.

Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
in this given variable in this is x.
What given?
yes because it doesn't have anything telling it not to
the independent variable
Dependent variable
Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
