How do you explain an equation?
What Is an Equation? An equation is a mathematical sentence that has two equal sides separated by an equal sign. 4 + 6 = 10 is an example of an equation. We can see on the left side of the equal sign, 4 + 6, and on the right hand side of the equal sign, 10.
How do you show work in math?
How to Show Your Work. When solving an equation, write down the equation and then show each step on a separate line below. If you divide both sides by 20, show that. If you add 2x²−3x to both sides, show that.
What do you need to know about solving equations?
Solving an equation is the process of getting what you’re looking for, or solving for, on one side of the equals sign and everything else on the other side. You’re really sorting information. If you’re solving for x, you must get x on one side by itself. Some equations involve only addition and/or subtraction.
What does an equation say about two things?
An equation says that two things are equal. It will have an equals sign “=” like this: That equations says: what is on the left (x − 2) is equal to what is on the right (4) So an equation is like a statement ” this equals that ” What is a Solution? A Solution is a value we can put in place of a variable (such as x) that makes the equation true.
How to substitute an equation for an answer?
To check, substitute your answer into the original equation: Solve for x. Add 11 to both sides. Divide each side by 5. To check, replace x with 8: Solve for x. Subtract 6 from each side. Multiply each side by . Solve for y. Add 8 to both sides. Multiply each side by . Solve for x. Subtract 2 from both sides (which is the same as adding –2).
How to check the answer to the equation y?
To check your answer, simply plug your answer into the equation: Solve for y. To solve this equation, you must get y by itself on one side. Therefore, add 9 to both sides. To check, simply replace y with 34: Solve for x. To solve, subtract 15 from both sides.
