find a solution method use backtracking to solve equation;
54=6 (47V)
_______
2
7b+1 =2
__________
4 8(56+12 1) =64
_____3______

How many equations are there? They are too jumbled up to make any sense. I see three equal signs and two unknowns.
What is the meaning out
_____3______ in the last line?
it looks like a fraction with no denominmator. 
the 3 is under 5b+12 1)=64

it was 3 questions.
and 2 is under the 47v and the 4 is under the7b+1 =2 .the 3 is under(56+12)=64
