20 = \frac{24}{a} a - 4

a \neq = 0

Solution steps

20 = \frac{24}{a} a - 4

Move

4

to the left side

24 = \frac{24}{a} a

Simplify

\frac{24}{a} a : 24

24 = 24

Both sides are equal

True for all a

Verify Solutions

Find undefined (singularity) points:

a = 0

Since the equation is undefined for:

0

a \neq = 0

x, y = \frac{z ^{3}}{a x}

\frac{x - 4}{2 x} + 1 = \frac{x + 3}{x}

\frac{6}{x} - \frac{5}{x - 6} + 1 = 0

1 - \frac{81}{x ^{2}} = 0

- 2 x + 4 = \frac{1}{3 x - 4}
