There is not enough information in the question to answer.
y can be any value, unless it is linked to x. The mathematical term would be that y is a function of x. For example, y(x) := 2 + 5x. In this case, y is a dependent variable (it depends on x), and it has a defined value for x = 3: y(1) = 2 + 5x3 = 17.
Without a known relation between y and x, however, y and x are independent and can assume any value.

X plus y equals 3 and y equals 3 - 2x?
x+y=3 y=3-2x so x+3-2x=3 so x=0 0+y=3 so y=3
What does x times x times x times x times x equal?
x5 You have x*x*x*x*x just add up the amount of x's you have and put it after as an exponent Example: 3*3*3*3=34 y*y*y*y*y*y=y6
What two numbers multiply to be 3 and add to -4?
-1
How do you complete the inverse of fx?
Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3
