What is the answer to 2b minus 4 over 6 equal to b minus 2 over 12?

2b - 4/6 = b - 2/12
change those fractions to common denominators for easy handling. 12 is good.
2b - 8/12 = b - 2/12
multiply through by 12
12/1(2b - 8/12 = b - 2/12)12/1
24b - 8 = 12b - 2
subtract 12b from each side
12b - 8 = - 2
add 8 to each side
12b = 6
divide both sides by 12
b = 1/2
--------------
check in original equation; keep as 6/12 (change to fraction, change fractions as needed )
2(6/12) - 8/12 = 6/12 - 2/12
12/12 - 8/12 = 6/12 - 2/12
4/12 = 4/12
