I know its probably easy but my brain hurts. I'm trying to work this prblem: y/-3=5-2y

Multiply both sides (of the = sign) by "-3".

 

[winsome]

y/-3 = 5-2y
Multiplying both sides by -3, we get
y = (5-2y)(-3)
y = -15+6y
5y = 15
y = 3

Winsome, please do not advertise "your" pay-for-tutoring services on these boards.

You wouldn't want to be confused with that low-life scum, Edith, would you? Right now, I'm trying very hard to see the difference.

Winsome, Losesome ...

\(\displaystyle Another \ way.\)

\(\displaystyle \frac{y}{-3} \ = \ 5-2y\)

\(\displaystyle \frac{y}{-3} \ = \ \frac{5-2y}{1}, \ now, \ cross \ multiplying \ gives:\)

\(\displaystyle y \ = \ -15+6y, \ 5y \ = \ 15, \ y \ = \ 3.\)

Hey, thanks for using "cross multiplication", BigG:
I always use it, but am often frowned upon for doing so; not sure why...
