Sorry typo error. should be
7xy + 4xy + x + y - 2y = 11xy + x - 1
is this correct
No.
What happened to y? Where did you get -1?
11xy + x - y
Is this correct?
Yes. It's correct now.
Thanks!
You're welcome.
To check if the given equation is correct, we can simplify both sides of the equation and see if they are equal. Let's begin by simplifying the left side of the equation:
7xy + 4xy + x + y - 2y
First, we can combine like terms by adding the coefficients of the same variables:
(7 + 4)xy + 1x + (1 - 2)y
This simplifies to:
11xy + x - y
Now, let's simplify the right side of the equation:
11xy + x - 1
Since there are no like terms to combine, the right side remains as is.
Now that we have simplified both sides of the equation, we can write the equation again:
11xy + x - y = 11xy + x - 1
By comparing the left and right sides of the equation, we see that they are indeed equal.
Therefore, the given equation: 7xy + 4xy + x + y - 2y = 11xy + x - 1 is correct.
