Question

3(5a+4b)-3a+b I need help with this problem. I just am really confused

Answer 1

12a + 13b

Explanation:

3(5a + 4b) - 3a + b

multiply 3 by 5a and 4b

15a + 12b - 3a + b

Now add the a terms together and b terms together

15a - 3a + 12b + b

12a + 13b

Answer 2

12a + 13b

Explanation:

3(5a+4b)-3a+b

To simplify the expression, we need to distribute the 3 to all terms inside the parentheses

3*5a+3*4b-3a+b

15a+12b-3a+b

Combine like terms

12a + 13b
