- How to verify 2y+30=8y?
- Relevant Equations
- 2y+30=8y
8y-2y=6y
6 y+30
6y/6=30/6
Y=5
Now how can I verify this equation?
6 y+30
6y/6=30/6
Y=5
Now how can I verify this equation?

What you're verifying is your solution. To do this, substitute the value you found for y into the original equation. By doing so, you should end up with a true statement, such as 7 = 7 for example.Rubies said:Problem Statement: How to verify the question?

Yes. That verifies that 5 is a solution of the equation 2y + 30 = 8y.Rubies said:So
I plunged in 5 to 6 or 6*5=30
30=30
You're very welcome, but take a good look at what I wrote in post #3 about organizing your work.Rubies said:Million thanks,to professionals in Science and Mathematics,who give up their time and help pupils like myself.
Actually, you should substitute your solution into the equation you were given to solve initially.Rubies said:So

30=30
Is it correct anyone
You mean "6y= 30"Rubies said:Problem Statement: How to verify 2y+30=8y?

However, it seems to me that it's the solution that's to be verified, rather than the equation. (A point of view consistent with your post.)symbolipoint said:...
Post #1 seems to now be adjusted to fit the expected homework help format.
To verify an equation, you need to check if both sides of the equation are equal when you substitute the given values for the variables. In this case, we can substitute any value for y and check if the equation holds true.
This equation means that the sum of 2 times y and 30 is equal to 8 times y. In other words, it is saying that the value of y is such that when multiplied by 2 and added to 30, it is equal to y multiplied by 8.
To solve this equation, we need to isolate the variable y on one side of the equation. We can do this by subtracting 2y from both sides, which gives us 30=6y. Then, we divide both sides by 6, and we get y=5 as the solution.
Yes, we can verify an equation with multiple variables by substituting values for all the variables and checking if both sides of the equation are equal. However, the number of variables should be equal to the number of equations to have a unique solution.
If the equation does not hold true when verified, it means that the given values for the variables do not satisfy the equation. In other words, there is no solution for the equation with those particular values. We may need to try different values or check if there is an error in the given equation.
