Now, see, that's the thing. That's actually why they give you the equation before
they ask you this question. The equation tells you exactly how 'x' and 'why' are
connected. So when you have the equation, you can answer the question, and
when you don't, you can't.
Notice that I don't. So I can't. But if I did, then I bet I could.
You already know the value of x is 4. To solve the value of y = 64x, mutlply 64 x 4. Hence, y = 64*4 = 256.
"X-4" is not an equation. It's just a number. Its value depends on the value of 'X'.
It depends on the value of X If we assume that the value of X is 22, then 22 + 4 = 26
4 x 4 x 4 = 64
x can have any value in the domain.
If you mean: 2*(x-4) = 73 then the value of x works out as 40.5
4 x 0.36 = 1.44
Start with y = |x|, then y = 4|x|, and then y = -4|x|.
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
If: x/-4 = 8 then x = -32
That depends on the value of x.
The value of y is y, as it will always be.
