-2=(7-3)/(2-x)

- 2 = \frac{7 - 3}{2 - x}

x = 4

Solution steps

- 2 = \frac{7 - 3}{2 - x}

Simplify

\frac{7 - 3}{2 - x} : \frac{4}{2 - x}

- 2 = \frac{4}{2 - x}

Multiply both sides by

2 - x

- 2 (2 - x) = 4

Divide both sides by

- 2

2 - x = - 2

Move

2

to the right side

- x = - 4

Divide both sides by

- 1

x = 4

Verify Solutions

Find undefined (singularity) points:

x = 2

Combine undefined points with solutions:

x = 4

\frac{x ^{3} + 1}{3 + x} = 60

2 t + \frac{4}{1 - t} = 0

\frac{20 x}{4 x - 1} + \frac{2}{x} = 5

\frac{12}{( y + 4 )} = 1

N = 50000 - \frac{2000}{t + 1}
