9x-6xy = 3
2xy + 6xy = 8xy
The "degree" is the highest power - in this case, the 3 in 4x3 (4 times to the third power).
If the question was -6xy = 0 - 6xy, then it is the additive identity property of 0. However, due to limitations of the browser used to post questions, most symbols are not visible to us. It is, therefore, difficult for me to be sure what your question was. Hoped I guessed correctly.
no or false
0.3333
18x^8y^4
6xy(2x2 - 3y)
9x-6xy = 3
2xy + 6xy = 8xy
yes 6xy is a monomial. A+LS
If that's +6xy, the answer is 2x(x + 3y) If that's -6xy, the answer is 2x(x - 3y)
6xy+9y2
-1
6xy +12y = 6y (x+2)
Totally pointless
5x33y4(6xy)-1First, the (6xy) can be moved to the bottom, and the 1 becomes positive. (And since anything to the first power is itself, the 1 goes away):5x33y4/(6xy)x3/x is x2 and y4/y is y3 and (5x3)/6 is 5/2, so this can be simplified to:(5/2)x2y3
