Answer:
Explanation:
To find w, we can substitute the equations y = 2z and z = 2w into the equation x = 2y to get the following:
x = 2(2z)
x = 4z
Since we know that z = 2w, we can substitute this into the equation x = 4z to get the following:
x = 4(2w)
x = 8w
Therefore, w = x / 8.
For example, if x = 16, then w = 16 / 8 = 2.
Another way to solve this problem is to use the following steps:
Start with the equation x = 2y.
Multiply both sides of the equation by 2 to get 2x = 4y.
Since y = 2z, we can substitute 2z for y in the equation 2x = 4y to get 2x = 4(2z).
Multiply both sides of the equation by 2 to get 4x = 8z.
Since z = 2w, we can substitute 2w for z in the equation 4x = 8z to get 4x = 8(2w).
Simplify the equation to get 4x = 16w.
Divide both sides of the equation by 4 to get w = x / 4.
Therefore, w = x / 8.
