Question: How to resolve: Warning, solutions may have been lost

Hi, I am trying to solve two simultaneous equations (for t1) they are as follows-

eq 1

i__m2(0) = (-(-b*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`+`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2-2*c)*exp(0)*a*N^alpha/`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^3+(-c*t__2^2*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2+b*t__2*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2+2*c*t__2*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`-b*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`+`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2-2*c)*exp(`#msub(mi("θ",fontstyle = "normal"),mi("m"))`*t__2)*a*N^alpha/`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^3)*exp(0)

eq 2

i__m1(t__1) = ((-c*t__1^2*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2+b*t__1*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2+2*c*t__1*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`-b*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`+`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2-2*c)*exp(`#msub(mi("θ",fontstyle = "normal"),mi("m"))`*t__1)*a*N^alpha*(lambda-1)/`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^3-(-b*`#msub(mi("θ",fontstyle = "normal"),mi("m"))`+`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^2-2*c)*a*N^alpha*(lambda-1)/`#msub(mi("θ",fontstyle = "normal"),mi("m"))`^3)*exp(-`#msub(mi("θ",fontstyle = "normal"),mi("m"))`*t__1)

rhs(i__m2(0) = (-(-b*theta__m+theta__m^2-2*c)*exp(0)*a*N^alpha/theta__m^3+(-c*t__2^2*theta__m^2+b*t__2*theta__m^2+2*c*t__2*theta__m-b*theta__m+theta__m^2-2*c)*exp(theta__m*t__2)*a*N^alpha/theta__m^3)*exp(0)) = rhs(i__m1(t__1) = ((-c*t__1^2*theta__m^2+b*t__1*theta__m^2+2*c*t__1*theta__m-b*theta__m+theta__m^2-2*c)*exp(theta__m*t__1)*a*N^alpha*(lambda-1)/theta__m^3-(-b*theta__m+theta__m^2-2*c)*a*N^alpha*(lambda-1)/theta__m^3)*exp(-theta__m*t__1))

solve({-(-b*theta__m+theta__m^2-2*c)*a*N^alpha/theta__m^3+(-c*t__2^2*theta__m^2+b*t__2*theta__m^2+2*c*t__2*theta__m-b*theta__m+theta__m^2-2*c)*exp(theta__m*t__2)*a*N^alpha/theta__m^3 = ((-c*t__1^2*theta__m^2+b*t__1*theta__m^2+2*c*t__1*theta__m-b*theta__m+theta__m^2-2*c)*exp(theta__m*t__1)*a*N^alpha*(lambda-1)/theta__m^3-(-b*theta__m+theta__m^2-2*c)*a*N^alpha*(lambda-1)/theta__m^3)*exp(-theta__m*t__1)}, [t__1]);
