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

x = \frac{15}{2}

Decimal Notation

x = 7.5

Solution steps

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

Cross multiply

8 x - 10 = 4 x + 20

Move

10

to the right side

8 x = 4 x + 30

x = \frac{15}{2}

Verify Solutions

Find undefined (singularity) points:

x = - 5

Combine undefined points with solutions:

x = \frac{15}{2}

t, a = \frac{S ^{2}}{2 t}

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

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

\frac{15}{4} = \frac{9}{2 r}

\frac{12 - 4}{5 ( x + 15 )} = 8
