+x%2F5+-+3+=+1%2F4+
The common denominator is 20
Multiply each side by 20
+20%2A%28x%2F5%29+-+20%2A3+=+20%2A%281%2F4%29+
+4x+-+60+=+5+
Add 60 to both sides
+4x+=+65+
Divide each side by 4
+x+=+16.25+
check answer:
+x%2F5+-+3+=+1%2F4+
+16.25%2F5+-+3+=+1%2F4+
Multiply both sides by 5
+16.25+-+15+=+1.25+
Add 15 to both sides
+16.25+=+16.25+
