++3%2F11+-+x%2F121+=+-1%2F142+
+%28+11%2F11+%29%2A%28+3%2F11+%29+-+x%2F121+=+-1%2F142+
+33%2F121+-+x%2F121+=+-1%2F142+
+%28+33+-+x+%29+%2F+121+=+-1%2F142+
Multiply both sides by +121%2A142+
+142%2A%28+33+-+x+%29+=+-121+
+4686+-+142x+=+-121+
+142x+=+4686+%2B+121+
+142x+=+4807+
+x+=+33.8521+
-------------------
check:
++3%2F11+-+x%2F121+=+-1%2F142+
+.27273+-+.008264x+=+-.007042+
+.008264x+=+.27273+%2B+.007042+
+.008264x+=+.279772+
+x+=+33.8543+
pretty close -error may be due to rounding off
