Answer 2

To simplify the expression 3(2x + 1) + 5(1 + 3x), you can distribute the coefficients:

First, distribute the 3 to the terms inside the parentheses: 3(2x + 1) becomes 6x + 3.

Next, distribute the 5 to the terms inside the parentheses: 5(1 + 3x) becomes 5 + 15x.

Now, you can combine like terms: 6x + 3 + 5 + 15x

Combine the constant terms (3 + 5) to get 8: 6x + 8 + 15x

Finally, combine the x terms (6x + 15x) to get 21x: 21x + 8

Therefore, the simplified expression is 21x + 8.
