Answer:

9b-14

Step-by-step explanation:

2(b-5)+7b-4

First you want to do what is in the parenthesis:

2 times b   2 times 5

The two is on the outside of the parenthesis which means you multiply it times the variable and the number.

Simply: 2b-10+7-+4

Now, you want to break the equation down. Both 7 and 2 have 'b' so you can add the two together.

2b+7b=9b

-10 and -4 can be put together. 4 is negative so you would subtract the two numbers.

-10-4= -14

Next, you want to take the two numbers 9b and -14 and put them into equation form.

9b-14

<u>I hope this helped! </u>

2(b-5)+7b-4
Solve 2(b-5) to get 2b-10
Combine your like terms 2b-10+7b-4
Solve 2b+7b to get 9b
Solve -10+(-4) to get -14
So your answer is
9b-14
