Try wrapping the first operand in a Ref to help Julia understand it is a “scalar”:
julia> Ref([10, 100]) .+ [[5, 5], [6, 6], [7, 7]]
3-element Array{Array{Int64,1},1}:
[15, 105]
[16, 106]
[17, 107]
This discussion contains a lot more details:
including some alternative ways of doing this, for example turning the “scalar” argument to a 1-Tuple:
julia> ([10, 100],) .+ [[5, 5], [6, 6], [7, 7]]
3-element Array{Array{Int64,1},1}:
[15, 105]
[16, 106]
[17, 107]
