((1.2-n))/((1-n))=1.4

\frac{( 1.2 - n )}{( 1 - n )} = 1.4

n = \frac{1}{2}

Decimal Notation

n = 0.5

Solution steps

\frac{( 1.2 - n )}{( 1 - n )} = 1.4

Simplify

\frac{( 1.2 - n )}{( 1 - n )} : \frac{1.2 - n}{1 - n}

\frac{1.2 - n}{1 - n} = 1.4

Multiply both sides by

1 - n

1.2 - n = 1.4 (1 - n)

Multiply both sides by

10

12 - 10 n = 14 (1 - n)

Expand

14 (1 - n) : 14 - 14 n

12 - 10 n = 14 - 14 n

Move

12

to the right side

- 10 n = - 14 n + 2

Move

14 n

to the left side

4 n = 2

Divide both sides by

4

n = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

n = 1

Combine undefined points with solutions:

n = \frac{1}{2}

\frac{( x - 3 )}{x} = \frac{( x + 3 )}{( x + 8 )}

\frac{2 x + 4}{5 x} = 23 x - 6

\frac{( 0.5 ( x ^{5} ) )}{( 5 x ^{3} - 2 x ^{2} + 3 x + 7 )} = 5

k \cdot l = \frac{6}{7 \cdot ( j + 6 k ) e}

(\frac{5 x}{4 x}) + 2 x = 6
