please help me solve this equation: if 3x-1=11, what is the value of 2x+x?
Thank you all in advance!!!!!! Can you please verify my answer?

Write in simplest form x^2+4x+4/x+2
= (x+2)(x+2)/x+2 = x+2

The x+2 on top and the x+2 on the bottom cancel out, leaving you with one x+2 left over. Is this correct?

Thanks so much for your help!
