4/(x-1-3)=1

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

x = 8

Solution steps

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

Simplify

\frac{4}{x - 1 - 3} : \frac{4}{x - 4}

\frac{4}{x - 4} = 1

Multiply both sides by

x - 4

4 = x - 4

Switch sides

x - 4 = 4

Move

4

to the right side

x = 8

Verify Solutions

Find undefined (singularity) points:

x = 4

Combine undefined points with solutions:

x = 8

22 = \frac{60}{y} + 2

\frac{x + 6}{x + 2} = - \frac{5}{x}

m, l = \frac{125}{m} + 50 n

\frac{x + 3}{x - 3} = \frac{15}{12}

x, 0.2 = \frac{x}{x + y}
