3-2/9b=1/3b-7
3 - 2/9b = 3/9b - 7
10 = 5/9b
10/(5/9) = b
3-2/9b=1/3b-7
What does b equal?

3-2/9b=1/3b-7
3 -2/9b = 1/3b -7
3+7 -2/9b = 1/3b -7 +7
10 -2/9b = 1/3b
10-2/9b +2/9b = 1/3b +2/9b
10 = (3+2)/9b
10 = 5/9b
Multiply both by 9b
10(9b) = 9b(5/9b)
90b = 5
Solve for b
90b/90 = 5/90
b = 1/18
3 -2/9b = 1/3b -7
3+7 -2/9b = 1/3b -7 +7
10 -2/9b = 1/3b
10-2/9b +2/9b = 1/3b +2/9b
10 = (3+2)/9b
10 = 5/9b
Multiply both by 9b
10(9b) = 9b(5/9b)
90b = 5
Solve for b
90b/90 = 5/90
b = 1/18
Either answer is correct, depending how how you interpret the original equation
