Question

P = x + 2y + 3z

solve for z

Answer 1

Okay, to solve for \(z\), we have to get it by itself.

\(P = x + 2y + 3z\)

We can subtract \(x\) to both sides:

\(P - x = 2y + 3z\)

Now we can subtract \(2y\) to both sides:

\(P - x - 2y = 3z\)

Do you know what we do next?

Answer 2

not really ^^'
i hardly understand the question.

Answer 3

divide 2y? @iGreen ?

Answer 4

You divide 3 to all the terms to the left. So what does that leave you with?

Answer 5

p - x - 2y
-------- = 3x
3

??

Answer 6

*not 3x just x, sorry.

Answer 7

@iGreen ?

Answer 8

anyone??

Answer 9

P = x + 2y + 3z .... solving for z--- subtract x from both sides
P - x = 2y + 3z --- subtract 2y from both sides
P - x - 2y = 3z --- now divide both sides by 3
(P - x - 2y) / 3 = z OR P/3 - 1/3x - 2y/3 = z

Answer 10

or P/3 - 1/3x - 2/3y = z

Answer 11

Yeah, that's correct. @silverr

Answer 12

yayy thank you so much you guys !
