Question

Solve the equation for y

4x -5y = 9


A. Y = 5/4x + 9/4

B. Y = -4x - 9

C. Y = 4/5x - 9/5

D. Y = -5/4x - 5/9

Answer 1

Make the equation \(4x-5y=9\) to \(y=mx+b\).

Answer 2

Okay

Answer 3

\(\huge 4x-5y=9\)

Subtract \(4x\) on both sides.
\( -4x+4x-5y=-4x+9\)

Then you'll get
\(\huge -5y=-4x+9\)

Now, divide \(-5\) on both sides.
\(\huge \frac{-5y}{-5}=\frac{-4x}{5}+\frac{9}{5}\).

Answer 4

Okay thank you

Answer 5

So, \(\huge y=\frac{-4x}{-5}+\frac{9}{-5}\)
OR
.\(\huge y=\frac{4x}{5}-\frac{9}{5}\) :D

Answer 6

You're welcome!

Just a correction: it should be -5 in my second reply. :)
