(5.6)/(0.4-r)=-8

\frac{5.6}{0.4 - r} = - 8

r = 1.1

Solution steps

\frac{5.6}{0.4 - r} = - 8

Multiply both sides by

0.4 - r

5.6 = - 8 (0.4 - r)

Switch sides

- 8 (0.4 - r) = 5.6

Divide both sides by

- 8

0.4 - r = - 0.7

Move

0.4

to the right side

- r = - 1.1

Divide both sides by

- 1

r = 1.1

Verify Solutions

Find undefined (singularity) points:

r = 0.4

Combine undefined points with solutions:

r = 1.1

\frac{3 ( a + 1 )}{a} = a

\frac{36}{b} - 3 = 0

\frac{2 x ^{2}}{x ^{4} + 1} = 1

\frac{x}{3} - 1 = \frac{6}{x}

\frac{3}{x} = 5
