x+7=-(12)/x

x + 7 = - \frac{12}{x}

x = - 3, x = - 4

Solution steps

x + 7 = - \frac{12}{x}

Multiply both sides by

x

x^{2} + 7 x = - 12

Solve

x^{2} + 7 x = - 12 : x = - 3, x = - 4

x = - 3, x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 3, x = - 4

y, y^{2} = \frac{x ^{2} - 49}{x ^{2} + 49}

f, - f = \frac{x}{x ^{2} + 1}

1 - \frac{2}{x + 1} = \frac{2 x}{x ^{2} + 3 x + 2}

2 x + \frac{3}{x + 2} = 1

\frac{1}{x} = \frac{1}{5} + \frac{3}{2 x}
