(45)/(x-2)=9

\frac{45}{x - 2} = 9

x = 7

Solution steps

\frac{45}{x - 2} = 9

Multiply both sides by

x - 2

45 = 9 (x - 2)

Switch sides

9 (x - 2) = 45

Divide both sides by

9

x - 2 = 5

Move

2

to the right side

x = 7

Verify Solutions

Find undefined (singularity) points:

x = 2

Combine undefined points with solutions:

x = 7

\frac{1}{x} = \frac{1}{x}

0 = 4 + \frac{5}{x ^{2} + 2}

\frac{3}{x + 8} = \frac{10}{2 x - 9}

\frac{m}{m + 1} + \frac{5}{m - 1} = 1

(1) = \frac{1}{s}
