Answer:


b=-2

Explanation:


-9+7b=8b-7\\-9+9+7b=8b-7+9 \leftarrow \text {Addition Property of Equality} \\7b+8b=2\\7b-8b+8b-8b=2\leftarrow \text {Subtraction Property of Equality} \\-b=2\\(-b)/(-1)=(2)/(-1) \leftarrow \text {Division Property of Equality}\\\boxed {b=-2}\\\\\huge\text {The value of 'b' should be -2}
