$m = 5$ $m=5$

Let's solve this equation step by step

Step 1: Cross-multiply.
$\frac{m - 1}{8} = \frac{2}{4}$ $(m-1)/8=2/4$
$4 m - 4 = 16$ $4m-4=16$

Step 2: Add 4 to both sides.
$4 m - 4 + 4 = 16 + 4$ $4m−4+4=16+4$
$4 m - 4 = 16$ $4m−4=16$
$4 m = 20$ $4m=20$

Step 3: Divide both sides by 4.
$\frac{4 m}{4} = \frac{20}{4}$ $(4m)/4=20/4$
$m = 5$ $m=5$

Check solution
$\frac{5 - 1}{8} = \frac{2}{4}$ $(5-1)/8=2/4$
