\frac{5 x - 45}{x - 9} = 5

x \neq = 9

Solution steps

\frac{5 x - 45}{x - 9} = 5

\frac{5 x - 45}{x - 9} : 5

5 = 5

Both sides are equal

True for all x

Verify Solutions

Find undefined (singularity) points:

x = 9

Since the equation is undefined for:

9

x \neq = 9

b, \frac{2 π}{b} = 4

\frac{200 x - 5000}{200 x} = 0.3

- 0.88 = \frac{550500 - 562750}{x}

6 \cdot \frac{x + 2}{x} = - 6

\frac{1}{2} (x + 4) = \frac{1}{3 x}
