Okay I understand that your ment to combine like terms but can someone help me understand this question better. Please.
9y-11-5y=25
9y-11-5y=25
Like terms are
those with y
those with only numbers
9y - 5y = 4y
Add 11 to both sides.
4y = 36

Thanks
You're welcome.
Of course, I can help you understand the given equation step by step.
The equation is: 9y - 11 - 5y = 25
Step 1: Combine like terms on the left side of the equation. In this case, the like terms are the y terms: 9y and -5y. When you subtract 5y from 9y, you get 4y.
So, the equation becomes: 4y - 11 = 25
Step 2: Now, to isolate the variable (y) on one side of the equation, we need to get rid of the constant term (-11) on the left side. To do that, we can add 11 to both sides of the equation.
When you add 11 to -11, they cancel each other out, leaving zero. So the equation becomes:
4y - 11 + 11 = 25 + 11, which simplifies to:
4y = 36
Step 3: Finally, to solve for y, we need to isolate the variable (y) on one side of the equation. Since 4y means "4 times y," we can do the opposite operation by dividing both sides of the equation by 4.
When you divide 4y by 4, you get y. And when you divide 36 by 4, you get 9.
So the solution is: y = 9.
Remember to always check the solution by substituting the value back into the original equation to see if it works. In this case, if you substitute y = 9 into the original equation, you get:
9 * 9 - 11 - 5 * 9 = 81 - 11 - 45 = 70, which is not equal to 25.
Therefore, it seems there might be a mistake in the given equation or there is no solution that satisfies the equation.
