What else can I help you with?
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 a square root equation?
To solve a square root equation, first isolate the square root term on one side of the equation. Then, square both sides to eliminate the square root. After squaring, solve the resulting equation for the variable. Finally, check your solutions to ensure they are valid, as squaring can introduce extraneous solutions.
What equations is parallel to y equals 4x plus 5?
A parallel equation has the same slope to the given equation. Note that your equation is in slope-intercept form; when an equation is solved for "y" (y = ...x + ...), the number in front of the "x" is the slope. Solve each of the other equations for "y" (if they are not already solved for "y"), and check the number in front of the "x".
What are the steps to solve a whole number equaiton?
To solve a whole number equation, follow these steps: Simplify both sides of the equation by combining like terms. Use inverse operations to isolate the variable on one side of the equation. Perform the necessary operations to solve for the variable. Check your solution by substituting the value back into the original equation to ensure it satisfies the equation.
How do you solve this equation and check you answer 2x-3y equals 8 x-2y equals 2?
x=10 y=4
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.
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 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.
What equation can be used to check 5 plus 4 equals 9?
Addiction
