3b + 787 - 93 x 9 + 98 = 0

3b + 787 - 747 + 98 = 0

3b + 40 + 98 = 0

3b + 138 = 0

3b + 138 - 138 = 0 - 138

3b = - 138

3b/3 = - 138 / 3

b = - 138 / 3

b = - 46

order of operations: PEMDAS-parentheses, exponents, multiplication, division, addition, subtraction
3b+787-747+98=3b+138

and if that equation is supposed to equal 0

3b+138=0
3b=-138
b=-46
