30b-15=-15-b
Use the distributive property to multiply 5 by 6b-3.
30b-15+b=-15
Add b to both sides.
31b-15=-15
Combine 30b and b to get 31b.
31b=-15+15
Add 15 to both sides.
31b=0
Add -15 and 15 to get 0.
b=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 31 is not equal to 0, b must be equal to 0.
