1/(x-7)=2

\frac{1}{x - 7} = 2

x = \frac{15}{2}

Solution steps

\frac{1}{x - 7} = 2

Multiply both sides by

x - 7

1 = 2 (x - 7)

Switch sides

2 (x - 7) = 1

Divide both sides by

2

x - 7 = \frac{1}{2}

Move

7

to the right side

x = \frac{15}{2}

Verify Solutions

Find undefined (singularity) points:

x = 7

Combine undefined points with solutions:

x = \frac{15}{2}

B, T = \frac{G}{B}

\frac{x ^{2} + x - 20}{x - 4} = x + 5

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

- \frac{3}{25} = \frac{15}{x}

\frac{9}{5} = \frac{w + 21}{w + 5}
