How do you solve this equation and check you answer 2x-3y equals 8 x-2y equals 2?
x=10 y=4
What is a check of a math equation?
I think you are referring to checking a math equation. After you solve an equation you should go back and check your work to make sure you got the right answer. You can do this by plugging your answer back into the equation
How do you solve feet if there is an X?
To solve for feet when there is an unknown variable (X), you first need to establish the relationship or equation that involves X and feet. For example, if you have a linear equation like (X + 5 = \text{feet}), you would isolate X by subtracting 5 from both sides. If you have a more complex equation, apply appropriate algebraic methods to isolate X and express it in terms of feet. Always ensure to check your solution by substituting back into the original equation.
How can you determine if a relationship is linear from a table a graph or an equation?
To determine if a relationship is linear from a table, check if the differences in the y-values (output) corresponding to equal differences in the x-values (input) are constant. For a graph, a linear relationship will appear as a straight line. In an equation, if the equation can be expressed in the form (y = mx + b), where (m) and (b) are constants, it indicates a linear relationship.
How do you solve radical equation and identify any extraneous roots?
To solve a radical equation, isolate the radical on one side of the equation and then square both sides to eliminate the radical. After squaring, simplify the resulting equation and solve for the variable. Finally, check all potential solutions by substituting them back into the original equation to identify any extraneous roots, which are solutions that do not satisfy the original equation.

How do you solve a whole number equation?
evaluate the equation, find the answer check the answer
When you find the value of a variable you solve or check an equation?
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
What is the extraneous solution to w equals sqrt 7w?
An "extraneous solution" is not a characteristic of an equation, but has to do with the methods used to solve it. Typically, if you square both sides of the equation, and solve the resulting equation, you might get additional solutions that are not part of the original equation. Just do this, and check each of the solutions, whether it satisfies the original equation. If one of them doesn't, it is an "extraneous" solution introduced by the squaring.
How do you solve word problems using variables?
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
How do you solve the equation 5n - 7 equals 38?
To solve the equation 5n - 7 = 38, do whatever you do to one side of the equals sign to the other. So, add 7 to both sides. 5n = 38. Now divide both sides by 9. 5 = 9. To check your answer, replace the n with 9 and solve the equation. 5 x 9 - 7 = 38. Do the multiplacation first. 45 - 7 = 38. 38 = 38. The answer is correct.
Solve each equation. Check the solution. You may find a model helpful.5 a equals 100?
(Since 5 times 20 does equal 100, the solution is correct.
What is used to solve a problem?
Trial and Error in science, or else you can use a (chemical) equation to solve and check.

How do you check your answer to an equation?
When you are solving an equation usually you are solving for x. If you want to check your answer just plug the values you got back in to the original function. Or you can use a different method to solve the equation and see if you get the same answer.
