$x=-2$

Refer to the explanation for the process.

Solve:

$2/(x+1)=4/x$

Cross multiply each denominator by the numerator of the opposite fraction.

$2x=4(x+1)$

Expland.

$2x=4x+4$

Subtract $2x$ from both sides.

$0=4x+4-2x$

Subtract $4$ from both sides.

$-4=2x$

Divide both sides by $2$ .

$-4/2=x$

Simplify.

$-2=x$

Switch sides.

$x=-2$
