It is an equation because it is telling you that one thing (or a combination of things) equates to something else.
There is not enough information to solve this equation however as there are an infinite number of solutions knowing only that 6x - 3y = 9.
Here are just 2: x = 2 and y = 1 or x = 3 and y = 3.
To solve this we need to know (or be able to calculate) the value of one of the variables first (either x or y) so that we can then calculate the other.
For this type of question (where there are 2 unknowns) you will usually either be told the value of one of the variables which you can then substitute into the equation, or you will be given two equations which are true for the same values of each variable (known as simultaneous equations). As the value for the two variables is the same in each equation we are able to use this extra information to solve them.
xy(3x - 2y)(2x + 3y)
I'm guessing its written like this---> 6x3y - 6x2y2 + 2x2y?Well, I'm guessing the answer is2x2y(3x - 3y + 1)This problem could not be solved if it was prime..Prime: If the letters and numbers don't match. (This is simply talking about the exponents)
9.
2, which equals 54. 3, which equals 36. 4, which equals 27. 6, which equals 18. 9, which equals 12. 12, which equals 9.
12 plus 9 equals 21.

81 divided by 9 equals 9
If x=9, x=9
9-8 equals = 1
9 out of 15 equals 60%
No! It equals 15, but 9-6=3.
9 out of 36 equals 25%
9
23-9 equals = 14
