The equation can be rewritten as: (in Math, it is advised that the order of terms be arranged. In this equation, the term 7b comes before constant 9 which is the correct arrangement.)

7b - 9 = 8b - 7

To solve, transpose 8b to the left and 9 to the right so the equation becomes:

7b -8b = 9 - 7

-b = 2

multiply both sides by -1 (to balance the equation) to make b positive:

-1(-b) = -1(2)

B= -2

To check:

7b - 9 = 8b - 7

7(-2) - 9 = 8(-2) - 7

-14 -9 = -16 -7

-23 = -23

The answers in both sides of the equation is equal therefore, YOU have derived to a CORRECT answer...
