You can put this solution on YOUR website!
+sqrt+%282x-5%29+%2B+3+=+12+
subtract 3 from both sides
sqrt%282x-5%29+=+9
square both sides
2x - 5 = 9^2
Add 5 to both sides
2x = 81 + 5
x = 86/2
x = 43

See if that checks out in the original equation
+sqrt+%282%2843%29-5%29+%2B+3+=+12+
+sqrt+%2886-5%29+%2B+3+=+12+
+sqrt+%2881%29+%2B+3+=+12+
9 + 3 = 12
