((x-1))/(2-(x+1)*0.3)=3

\frac{( x - 1 )}{2 - ( x + 1 ) \cdot 0.3} = 3

x = 3.21052 \dots

Solution steps

\frac{( x - 1 )}{2 - ( x + 1 ) \cdot 0.3} = 3

Simplify

\frac{x - 1}{2 - ( x + 1 ) \cdot 0.3} : \frac{x - 1}{- 0.3 x + 1.7}

\frac{x - 1}{- 0.3 x + 1.7} = 3

Multiply both sides by

- 0.3 x + 1.7

x - 1 = 3 (- 0.3 x + 1.7)

Expand

3 (- 0.3 x + 1.7) : - 0.9 x + 5.1

x - 1 = - 0.9 x + 5.1

Move

1

to the right side

x = - 0.9 x + 6.1

Move

0.9 x

to the left side

1.9 x = 6.1

Divide both sides by

1.9

x = 3.21052 \dots

Verify Solutions

Find undefined (singularity) points:

x = \frac{17}{3}

Combine undefined points with solutions:

x = 3.21052 \dots

\frac{x}{( x ^{2} - 9 )} + \frac{4}{( x + 3 )} = \frac{3}{( x ^{2} - 9 )}

\frac{4 ( ( x + 1 ) ( 2 x + 5 ) - 2 x ^{2} - 5 )}{( x - 2 )} = 3

x^{- 1} = 0.1 x

\frac{z ^{2} - 4 a ^{2} - 2 - 1}{z ^{2}} = 0

18 t = \frac{0 + 1}{2 ( 3 ) t ^{2}}
