Question

how would you solve this equation: 7x-1=3y+8

Answer 1

In slope intercept form?

Answer 2

yes

Answer 3

use the same technique as your other equations. You can start by subtracting 8 from both sides. I will help you along the way, but try to work through it.

Answer 4

ok so
7x-1=3y+8
-8 -8

-1x-1=3y

Answer 5

8 is not multiplied by x, so you cannot subtract it from 7x. It would instead be 7x-1-8=7x-9. Make sense?

Answer 6

oh ok understand now thank you!

Answer 7

No problem. Post your answer if you want confirmation.

Answer 8

is the answer: y=7x-3? or y=7x-9?

Answer 9

The first one is closest, but you forgot to divide all parts by 3...

7x-9=3y

You have to divide all of it:
(7x-9)/3

Answer 10

so y=7/3x-3?

Answer 11

Yep - that's it!
