Step-by-step explanation:
.
x=1001+75.55x
Simplify
x=<span><span>75.55x</span>+1001</span>
Subtract
x−<span>75.55x</span>=<span><span><span>75.55x</span>+1001</span>−<span>75.55x</span></span>
−<span>74.55x</span>=1001
Divide
<span><span>−<span>74.55x/</span></span><span>−74.55 = </span></span>
<span><span><span><span><span>1001/<span>−74.55</span></span><span><span>your answer is:</span></span><span>x=<span>−<span>13.42723</span></span></span></span></span></span></span>
