If your system is
x - y = 120
x + y = 150
I would use elimination. Adding the two equations together gives us
2x = 270
and dividing by two tells us that x = 135. Plug x back into either equation to find y:
x + y = 150
135 + y = 150
y = 15
So x = 135 and y = 15.

sorry, it is wrong the answer is : y=k/x2(square) {when y = x we will write y as x and leave x2(square) alone. like this: x=120/x2(square) x multiply by x2(square) is x3(cube) so cube root of 120 = x so x is 4.93
Both. If you look at it like this: y=41-x you say x is independent and y is dependent of x (i.e. y is a function of x) For x=41-y you say y is independent and x is dependent of y (i.e. x is a function of y)
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
