Question

Π=7x−2y can someone please help to find y

Answer 1

In π = 7x - 2y we first isolate y by adding 7x on both sides.
This gives us π + 7x = -2y. Divide 2 on both sides, then we are left with:

y = $-\frac{ \pi - 7x}{2}$

Answer 2

Hey!

First, let's write the problem.
$\pi =7x-2y$
Let's switch sides to make it easier. 
$7x-2y=\pi$
Subtract $7x$ from both sides.
$7x-2y-7x=\pi -7x$
$-2y=\pi -7x$
Divide both sides by -2.
$\frac{-2y}{-2}=\frac{\pi }{-2}-\frac{7x}{-2}$

We know that, $\frac{\pi }{-2}-\frac{7x}{-2}=-\frac{\pi -7x}{2}$, so let's plug that in on our final answer. That would be,

$y=-\frac{\pi -7x}{2}$

Thanks!
