Simplify the expression: 5(2x + 3) - 3x.

Explanation:
To simplify the expression 5(2x + 3) - 3x, start by distributing the 5 into the parentheses: 5(2x) + 5(3) results in 10x + 15. Now, rewrite the expression with this result: 10x + 15 - 3x. Next, combine like terms. The like terms here are 10x and -3x. Subtracting 3x from 10x gives you: 10x - 3x = 7x. Now, bring down the constant term 15: 7x + 15. Therefore, the final simplified expression is 7x + 15, which is why this choice is correct.

To simplify the expression 5(2x + 3) - 3x, start by distributing the 5 into the parentheses:

5(2x) + 5(3) results in 10x + 15.

Now, rewrite the expression with this result:

10x + 15 - 3x.

Next, combine like terms. The like terms here are 10x and -3x. Subtracting 3x from 10x gives you:

10x - 3x = 7x.

Now, bring down the constant term 15:

7x + 15.

Therefore, the final simplified expression is 7x + 15, which is why this choice is correct.
