Question

Solving equations and Formulas for a variable.
x+5y = 45
Solve for y.

Answer 1

My answer is \[y =- \frac{ 1 }{ 5 } x + 9\]

Answer 2

looks good to me!

Answer 3

How is that wrong?!

Answer 4

You have to isolate y. To do that, first subtract x from both sides. \(5y=45-x\)

Answer 5

Well, I got it wrong so I do not understand on what I'm missing.

Answer 6

what else could it be?

Answer 7

Then, divide both sides by 5.

Answer 8

\[x+5y=45\\
5y=-x+45\\
y=-\frac{x}{5}+9\]
