Explanation:

because it's the same format

Answer 2

Explanation:

It ain't that hard. Let's take the first one:

y = 4x + 2z

If you wanna make x the subject, you try to get rid of anything by its side. In other words:

`y = 4x + 2z \\ y - 2z = 4x + 2z - 2x \\ y - 2z = 4x \\ (y - 2z)/(4) = (4x)/(4) \\ x = (y - 2z)/(4)`

Everything boils down to 2 easy steps:

• add or substract to get rid of all the other terms near what you want
• devide by the coefficient

Now let's check the second example:

`z = (x)/(4) + 2 \\ z - 2 = (x)/(4) \\ 4 * (z - 2) = 4 * (x)/(4) \\ x = 4(z - 2)`

That's it :)
