Question

Can someone help

Answer 1

Step-by-step 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:

$y = 4x + 2z \\ y - 2z = 4x + 2z - 2x \\ y - 2z = 4x \\ \frac{y - 2z}{4} = \frac{4x}{4} \\ x = \frac{y - 2z}{4}$

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:

$z = \frac{x}{4} + 2 \\ z - 2 = \frac{x}{4} \\ 4 \times (z - 2) = 4 \times \frac{x}{4} \\ x = 4(z - 2)$

That's it :)
