Solve {l}{y-x/x^2-1x=2}{x=3}

$$\left. \begin{array}{l}{ y - \frac { x } { x ^ { 2 } - 1 } x = 2 }\\{ x = 3 }\end{array} \right.$$

Solve for y, x

$$x=3$$

$$y = \frac{25}{8} = 3\frac{1}{8} = 3.125$$

Solution Steps

Consider the first equation. Insert the known values of variables into the equation.

$$y-\frac{3}{3^{2}-1}\times 3=2$$

Calculate 3 to the power of 2 and get 9.

$$y-\frac{3}{9-1}\times 3=2$$

Subtract 1 from 9 to get 8.

$$y-\frac{3}{8}\times 3=2$$

Multiply \frac{3}{8} and 3 to get \frac{9}{8}.

$$y-\frac{9}{8}=2$$

Add \frac{9}{8} to both sides.

$$y=2+\frac{9}{8}$$

Add 2 and \frac{9}{8} to get \frac{25}{8}.

$$y=\frac{25}{8}$$

The system is now solved.

$$y=\frac{25}{8} x=3$$
