(10-4)/(a-3)=2

\frac{10 - 4}{a - 3} = 2

a = 6

Solution steps

\frac{10 - 4}{a - 3} = 2

Simplify

\frac{10 - 4}{a - 3} : \frac{6}{a - 3}

\frac{6}{a - 3} = 2

Multiply both sides by

a - 3

6 = 2 (a - 3)

Switch sides

2 (a - 3) = 6

Divide both sides by

2

a - 3 = 3

Move

3

to the right side

a = 6

Verify Solutions

Find undefined (singularity) points:

a = 3

Combine undefined points with solutions:

a = 6

\frac{6}{2 x - 5} - \frac{4}{x - 3} = 0

4 + \frac{7}{c} = \frac{5}{3}

\frac{x}{x + 1} + \frac{4}{x} = 0

\frac{1}{x} = 0.4285714286

\frac{25}{2} = \frac{100}{x}
