3/(b-4)= 9/3

\frac{3}{b - 4} = \frac{9}{3}

b = 5

Solution steps

\frac{3}{b - 4} = \frac{9}{3}

Cross multiply

9 = (b - 4) \cdot 9

Switch sides

(b - 4) \cdot 9 = 9

Divide both sides by

9

b - 4 = 1

Move

4

to the right side

b = 5

Verify Solutions

Find undefined (singularity) points:

b = 4

Combine undefined points with solutions:

b = 5

\frac{4}{5 - 2 x} = \frac{3}{3 x - 1}

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

x + \frac{3}{x} = 4
