If you have letters together, like xy +2, it means you multiply
In Algebra, "is" means Equal (=).
It means "not equal to".
xy - xy = 0
There are quite a few, but here are some:The distributive x(y+z)=xy+xzThe associative x+y=y+xand many others!
xy+xy'
(-5xy):(-xy)=
The sum of xy times 3 is equal to 3(xy).
If you have letters together, like xy +2, it means you multiply
() x=y(x)xy(x)(x)=() (). X=
In Algebra, "is" means Equal (=).
This equation does not equal a number, but it can be factorised. x2-xy-20y2=(x-5y)(x+4y)
If x - 3y = 12, we can solve for x in terms of y: x = 12 + 3y. Then, to find xy, we multiply x by y: xy = y(12+3y) = 12y + 3y^2.
That is irrelevant, there is not possible way y=xy, and there is no possible way xy=x.
It should equal 24.
It equals XY.
