1/9x + 3= -1

I put 1/9x =2
X=18

Check your answer by substitution. Is it right?

No

1/9x + 3= -1

Subtract 3 from both sides. What do you get>

1/9x = ?

X=2

1/9x= -4

Nope.

1/9x = -4

Divide both sides by 1/9

X= -36

Let's substitute and see if it's right.

1/9x + 3= -1

(1/9) * -36 = -4

-4 + 3 = -1

Yes! x = -36

Thanks

You're welcome. :-)
