A) -24

Step-by-step explanation:

$\frac{3}{5}x+8=\frac{1}{10}(x-40)\\\\\frac{3}{5}x+8=\frac{1}{10}*x-\frac{1}{10}*40\\\\\frac{3}{5}x+8=\frac{1}{10}x-4\\\\\frac{3}{5}x-\frac{1}{10}x+8=-4\\\\\frac{3*2}{5*2}x-\frac{1}{10}x=-4-8\\\\\frac{6}{10}x-\frac{1}{10}x=-12\\\\\frac{6-1}{10}x=-12\\\\\frac{5}{10}x=-12\\\\\frac{1}{2}x=-12\\\\x = -12*2\\\\x = -24$
