What is an algebraic expression? It is made up of signs and symbols of algebra. Arabic numerals literal numbers the signs of operation +,-,/,*,=

What is the variable? A letter that represents a value in an algebraic expression. X+4- the variable is X and X=7 Now you need to solve the problem.

Solve X+4 if X= 7 Therefore you would need to insert the number 7 where X is if X=7. So 7+4=? 11 is the answer

Congratulations You have just solved an algebraic expressing with one variable. Other problems may tougher and will use other signs such as subtraction, multiplication, and division. You will still apply the same concepts you did with problem. Now you are ready to move on to the next step in math education.
