which four

HaydenwH:

ok, so you know y=6 so you will take your equation 6y-1 plug your y in which would be 6(y)-1 if y= 6 then plug it in and solve it

ChrisTheFlash:

the first 4 questions

ChrisTheFlash:

6(6)-1(6) is that right?

ChrisTheFlash:

so 36-36

ChrisTheFlash:

is 0

HaydenwH:

why did you sub the second 6?

HaydenwH:

there is only 1 "y" in the problem, so you only sub (6) where there is a "y"

Katrin369:

If there is only on y, then replace the y with the 6 you don't have to put two extra y's in the equation.

HaydenwH:

6(6)-1

ChrisTheFlash:

it was 35

HaydenwH:

yes

Katrin369:

Now, 35 - 1.

ChrisTheFlash:

Katrin369:

Okay here lets do the 9 *w first.

no, 6(6) is 36, and 36-1 =35

6x6 = 36 When you subtract 36 from 1 you get 35, I think u did that wrong

Katrin369:

W = 8
