Answered by MonsieurBrainly

$\frac{1.2x+3}{3.2x+6} = \frac{9}{8} \\\\ 8(1.2x+3) = 9(3.2x+6)\\\\ 8 \times 1.2x+8\times 3 = 9\times 3.2 + 6\times 9 \\\\ 9.6x+24 = 28.8x+54 \\\\ 28.8x-9.6x= 24-54 \\\\ 19.2x = -30 \\\\ x = -\frac{30}{19.2}\\\\ x = -\frac{\cancel{300}}{\cancel{192}} \\\\ x= - \frac{25}{16}$

$\bold{\boxed{ x\: = \: - \frac{25}{16}}}$
