Expressions and Equations Worksheets

What is the Difference Between Expressions and Equations? When you are learning algebra, finding out the difference between expressions and equations is essential. Although, in hindsight, both of these are relatively similar; however, there are distinct differences between the two. Let us discuss the differences in the table below. What are equations? - The equation is a mathematical statement that has two expressions with a relational operator connecting them. Most questions deal with satisfying both sides by finding out the value of the unknown present in the equation. There are numerous examples of equations. You have the quadratic equation, linear equation, cubic equation, and so on. An answer to an equation usually deals with whether the comparison is true or false in terms of the relational operator. What are expressions? - The expression is a mathematical phrase that connects numbers, variables, and operators for showing the value of something. It represents the value of something. In other words, if you get asked what a person's age is, then an expression is Person' s age=20 years The examples of expression are 9x - 3, 5y + 3, etc. While the answer to expression is a numerical value. A super common question is the difference between expressions and equations. Expressions can be evaluated, but never truly have a single solution. The evaluation of expressions change based on the variables involved. Equations can be solved and often the make two expressions equal.
Expression: 8x + 12 (Different solutions based on the value of x)
Equation: 8x + 12 = 52 (There is only 1 value for x)
