Best Answer

Presumably this is a simultaneous equation in the form of:

x = 8-2y

y-x = 4

Which is the same as:

2y+x = 8

y-x = 4

Add both equations together:

3y = 12.

So y will equal 4.

Substitute the value of y into the original equations to find the value of x:

So: x = 0 and y = 4

The only integer n where n equals xy equals yx and x does not equal y?

This gives us the equations: n = xy = yx x != y (Note that for this example, the != stands for not equal to similar to some programming languages.) xy always equals yx due to the communtative property of multiplication. So there are actually an infinite number of answers. Some are given below: 6 = (2)(3) = (3)(2), 2 != 3 12 = (3)(4) = (4)(3), 3 != 4

What is xy plus x plus 3y plus 3?

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----
