Question

solve this equation for y
5x - 7y = 10
a. y= -7/5x - 7/10
b. y= 7/5x + 10/5
c. y- 5/7x - 10/7
d. y= -5x - 7

Answer 1

@Nurali

Answer 2

5x - 7y = 10
5x-10=7y
y=?

Answer 3

Answer 4

Divide by 7

Answer 5

You typed faster than me :( XD @Nurali

Answer 6

Im still lost.

Answer 7

You got it to \[5x-10=7y\] You have to divide both sides by 7, What you do to one side, you have to do to the other side.

Answer 8

Then you must isolate Y
So
\[5x-7y-10\]

Answer 9

\[-7y=-5x-10\] You have to change \[5x\] to this side as negative.

Answer 10

Then divide by -7 and you end up with \[y= 5/7x-10/7\] So theres your answer! Any questions?
