Answer:
2b-18
Explanation:
First you would need to use the distributive property in 6(2b-3)-10b.
You would distribute the 6 and multiply it by the equation in the parenthesis, so the outcome of the equation would be (12b-18)-10b. Then you would combine like terms, so you would subtract 10b from 12b. Your final simplified equation would be 2b-18.
