i did that and i just dont understand how to fully solve the question. i keep coming up with obscure numbers and i dont think they are correct.

6.5y - 9 = 11 6.5y = 20 3.07=y

Originally Posted by chinese_man_77 i dont know, i tried like 8 different things. i dont get it. i give up $\displaystyle 3x + 5y = 11$ $\displaystyle 3\left[\frac{3(y-6)}{2}\right] + 5y = 11$ $\displaystyle \frac{9(y-6)}{2} + 5y = 11$ $\displaystyle 9(y-6) + 10y = 22$ finish it.
