How to find the value of b Solving equation containing Erf expressions

Given the equation below, how do I find the value of bb so that the function is equal to 21. I tried solve but I keep getting an error message. Thank you.

(15 Sqrt[\[Pi]]Sqrt[π] (Erf[11 Sqrt[b]] + Erf[17 Sqrt[b]]))/(14 Sqrt[b])==21 == 21
