What does it mean to substitute a given value for each variable in an algeraic expression?
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
What is an algebraic expression by replacing each variable with a given number and performing all operations?
It is called evaluating the equation.
What operations could you perform on both sides of the given equation to solve it?
normally when people say "which of the following" there are actually choices following it below...
What is a subsitute given value for each variable in an algebraic expression?
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
What name is given to the variable you plot on the x-axis?
The independent variable
How do you do evaluate expression?
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.

Evaluate the variable expression for x equals 3?
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.
What is the given variable to -132x-3 12x-4?
in this given variable in this is x.

Is it true for a computer to perform operations it must be given a set of instructions that tells its exactly what to do?
yes because it doesn't have anything telling it not to
What is given to the variable we plot on the x-axis?
