This TRS is terminating using the deltasimple interpretation 
minux(delta2, X3) =  + 1*X3 + 0 + 0*X3*delta2 + 3*delta2
minus(delta1, X2) =  + 1*X2 + 0 + 0*X2*delta1 + 1*delta1
+(delta0, X1, X0) =  + 1*X0 + 1*X1 + 0 + 0*X0*delta0 + 0*X1*delta0 + 0*delta0
minux_tau_1(delta2) =  + (delta2/(1 + 0 * delta2))
minus_tau_1(delta1) =  + (delta1/(1 + 0 * delta1))
+_tau_1(delta0) =  + (delta0/(1 + 0 * delta0))
+_tau_2(delta0) =  + (delta0/(1 + 0 * delta0))
