solve:

3(y-6)=2x
3x+5y=11

any help would be great appreciated, thanks.

substitute $\frac{3(y-6)}{2}$ for x into the second equation and solve for y

3. 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.

post what you did ...

5. 6.5y - 9 = 11
6.5y = 20
3.07=y

$3x + 5y = 11$

$3\left[\frac{3(y-6)}{2}\right] + 5y = 11$

$\frac{9(y-6)}{2} + 5y = 11$

$9(y-6) + 10y = 22$

finish it.
