If you mean X multiplied by Y, then you can just enter XY, and press enter. of course you first have to enter values for X and Y with: (number)->X (number)->Y (->) is a representation of the STO> key.
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
I don’t know

Neither. It is a family of hyperbolae.
What is the solution set for the equations x-y=2 and -x+y=2
-4
The problem to solve is: xy+x+3y+3 Multiply y and x Multiply the y and x Multiply y and x The y just gets copied along. The x just gets copied along. The answer is yx yx x*y evaluates to yx x*y+x evaluates to yx+x Multiply y and 3 Multiply y and 1 The y just gets copied along. The answer is y y 3*y evaluates to 3y The answer is yx+x+3y x*y+x+3*y evaluates to yx+x+3y The answer is yx+x+3y+3 x*y+x+3*y+3 evaluates to yx+x+3y+3 ---- The final answer isyx+x+3y+3----
24/yx there isn't an = sign
It is not possible to answer the question because there is no equation - only an expression.
If you mean y = x+5 and y = x+9 then both slopes will be parallel but with different y intercepts
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
The two variables are in inverse proportion and, graphically, will form a hyperbola.
