Question

HELLPP!
how do i "find the equation for y"?
5x - 7y = 10

Answer 1

it's multiple choice

Answer 2

You have to get 'y' by itself on one side, start by subtracting 5x to both sides.

Answer 3

-7y=10-5x ?

Answer 4

Yep!

Now divide -7 to both sides.

Answer 5

Yes, and then you can divide both sides by -7 to isolate y. Then you have the equation for y ;)

Answer 6

mmm.... k so y=(how do i divide this side by -7?)

Answer 7

@iGreen

Answer 8

\(-7y = 10 - 5x\)

\(\dfrac{-7y}{-7} = \dfrac{10}{-7} = \dfrac{5x}{-7}\)

Answer 9

Sorry there should be a subtraction side on the right, not an equal sign.

Answer 10

When you divide each side by -7, you're getting the y by itself while still keeping the -7 part of the equation

Answer 11

Yes, the -7's on the left cancel out, giving us:

\(y = \dfrac{5}{7}x - \dfrac{10}{7}\)
