Sparingly Soluble Salt Electrode Potential

MX is a sparingly soluble salt that follows the given solubility equilibrium at 298 K
$MX(s)\xrightleftharpoons{{}}{M^ + }(aq) + {X^ - }(aq)$ ; K_sp = 10^–10
If the standard reduction potential for
${M^ + }(aq)\xrightarrow{{ + {e^ - }}}M(s)$ is $\left( {E_{{M^ + }/M}^ \ominus } \right) = 0.79V$ , then the value of the standard reduction potential for the metal/metal insoluble salt electrode $E_{{X^ - }/MX(s)/M}^ \ominus$ is _________ mV. (nearest integer)
[Given: $\frac{{2.303RT}}{F} = 0.059V$ ]
