4-x/(x-4)= 5/(x-4)

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

x = 7

Solution steps

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

Multiply both sides by

x - 4

4 (x - 4) - x = 5

Expand

4 (x - 4) - x : 3 x - 16

3 x - 16 = 5

Move

16

to the right side

3 x = 21

Divide both sides by

3

x = 7

Verify Solutions

Find undefined (singularity) points:

x = 4

Combine undefined points with solutions:

x = 7

\frac{- 54}{w} = 6

y, x = y^{- 3}

y, x = y^{- 2}

2 x - \frac{7}{x + 6} = x

191000 = \frac{1}{2 π \cdot 20 \cdot x}
