Alice hit 10 and peter hit 8.

Explanation:

Let #A# = Alice's runs.
Let #P# = Peter's runs.
#P = 2(A - 6)# Twice the difference of the number of runs Alice hit and 6.
#P + A = 18# Total number of home runs.
Substituting for #P# in #(P + A = 18#):
#2(A-6) + A = 18 => 3A = 30 => A = 10#
If #A = 10# then # P + 10 = 18 => P = 8#
