((1+x))/((11-x))= 1/3

\frac{( 1 + x )}{( 11 - x )} = \frac{1}{3}

x = 2

Solution steps

\frac{( 1 + x )}{( 11 - x )} = \frac{1}{3}

Cross multiply

3 + 3 x = 11 - x

Move

3

to the right side

3 x = - x + 8

Move

x

to the left side

4 x = 8

Divide both sides by

4

x = 2

Verify Solutions

Find undefined (singularity) points:

x = 11

Combine undefined points with solutions:

x = 2

x, 9 \frac{y}{x} = 2

x, x^{2} + (y - \frac{4}{x ^{2}}) 2 = 2

\frac{( n + 2 ) !}{n !} - \frac{n !}{( n - 2 ) !} = 30

\frac{x ^{2} + 1}{( x ^{2} )} = 2

x^{2} - 1 = x - 3
