There is a number here which we don't know, so we will call it x.
Twice that number is the same as saying 2x.
So... 2x + 3 > 49
Now we solve as if it was an equation. We add -3 to both sides and we get...
2x > 46
We divide both sides by 2 to isolate x...
x > 23
There you go. Any number greater than 23 is a correct answer to your problem. Let's verify by substituting x for 24.
2(24) + 3 > 49
48 + 3 > 49
51 > 49
Yep! It checks!

Let the unknown number = +n+
given:
+2n+%2B+3+%3E+49+
Subtract +3+ from both sides
+2n+%3E+46+
Divide both sides by +2+
+n+%3E+23+
-----------------------
You can check this by first letting
+n+=+23+
+2n+%2B+3+%3E+49+
+2%2A23+%2B+3+%3E+49+
+49+%3E+49+ not true
---------------------
Next let +n+=+24+
+2%2A24+%2B+3+%3E+49+
+51+%3E+49+ true
So, the answer looks correct
