Step 1. Multiply both sides by cx+d
<span>ax+d = e (cx+d) </span>
<span>Step 2. Distribute </span>
<span>ax+b = ecx + ed </span>
<span>Step 3. Subtract b from both sides </span>
<span>ax = ecx + ed - b </span>
<span>Step 4. Subtract ecx from both sides </span>
<span>ax - ecx = ed - b </span>
<span>Step 5. Factor our x from the right side </span>
<span>x(a-ec) = ed - b </span>
<span>Step 6. Divide both sides by a-ec </span>
<span>x = (ed-b) / (a-ec)</span>
