HP 48GX based on C.Ret one,
(flag 3 unchecked = symbolic function)

[L] SOLVE [_ROOT_softkey] 3 (left SOLVE is hidden on keyboard)
alpha A [L]x^2 alpha A + alpha B [R]LN - 12
alpha B [L] X^2 [R] LN [L] = 8
[L] [EQ softkey] 2 (equivalent to STO into EQ)
[_SOLVR softkey] 1 (activate Solvr menu with 'white' softkeys)

Total : 3+12+8+2+1 = 26

Differently and shorter :
' alpha A y^x 2 + alpha A [R]= [R]LN alpha B y^x 2 16
[L] [EQ softkey] 2

Total : 3 + 16 + 2 + 1 = 22

Regarding results : the 'EXPR=' white softkey returns tagged values on 2 lines :
2: Left: value
1: Right: value
hence only one "EXPR=" white softkey is necessary for each pair of result values
