Uit \(\boldsymbol{\frac {x\,+\,1} {y} = 2} \) volgt dat	A. \(\boldsymbol{x=2y-1 }\)
B. \(\boldsymbol{x=2y }\)
C. \(\boldsymbol{\frac 2y = x+1 }\)
D. \(\boldsymbol{x+\frac 1y = 2 }\)
E. \(\boldsymbol{x=2(y-1) }\)

From $\boldsymbol{\frac {x\,+\,1} {y} = 2} $ follows	A. $\boldsymbol{x=2y-1 }$
	B. $\boldsymbol{x=2y }$
	C. $\boldsymbol{\frac 2y = x+1 }$
	D. $\boldsymbol{x+\frac 1y = 2 }$
	E. $\boldsymbol{x=2(y-1) }$

$\frac{x+1}{y}=2\; \Leftrightarrow\; x+1=2y\;\Leftrightarrow\; x=$
