ABA6+4116=12156

Although there are other ways to do this, I would start by converting the two right values to base ten.

The now converted equation is:

ABA6+15110=29910

If we then subtract 151 from both sides, we get:

ABA6=148
We can then use the equation 36A+6B+A=148, which simplifies to 
37A+6B=148

The only non-extraneous values that work for this equation are A=4 and B=0

4-0=4, which makes the answer 4.
