Question

Solve the formula for the variable y.

z = 4x + 2y

Answer 1

z=4x+2y
-4x from each side
z-4x = 2y
divide each side by 2
\[\frac{ z-4x }{ 2 }\]

Answer 2

that equals y

Answer 3

y=z/2 - 2x

Answer 4

im confused

Answer 5

thanks for the help guys !

Answer 6

z - 4x = 2y
\[y = \frac{ z-4x }{ 2 }\]
y = \[y = \frac{ 1 }{ 2 }z - 2\]

Answer 7

z = 4x + 2y, solve for Y

Move the Z and X variables to the same side of the equation by subtracting 4x from both sides, that leaves you with:

z - 4x = 2y

To isolate the y variable by itself on that side of the equation, divide both sides by 2, so:

(z-4x)/2 = y

This can be simplified to: (z/2) - 2x = y
