Answer

$x=1.\overline{2497}$

Work Step by Step

Using the properties of equality, the solution to the given equation, $ 8.43x-2.5(3.2-0.7x)=-3.455x+9.04 $, is \begin{array}{l} 8.43x-8+1.75x=-3.455x+9.04 \\\\ 8.43x+1.75x+3.455x=9.04+8 \\\\ 13.635x=17.04 \\\\ x=\dfrac{17.04}{13.635} \\\\ x=1.\overline{2497} .\end{array}
