4 x 0.36 = 1.44
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
2,200 x .036 (3.6%) = 79.2
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.
