Answer 2

∆ Question -:

Solve -: 13 (z - 4) - 3 (z - 9) - 5 (z + 4) = 0.

$\blue\star$ Answer -:

$13 \: (z - 4) - 3 \: (z - 9) - 5 \: (z + 4) = 0$

$13z - 52 - 3z - 27 - 5z + 20 = 0$

$13z - 3z - 5z - 52 - 27 + 20 = 0$

$10z - 5z - 25 + 20 = 0$

$5z - 45 = 0$

$5z = 0 + 45$

$5z = 45$

$z = \frac{45}{5}$

$z = 9$
