you forgot the 5x in the 2nd line

(13 x+ 10y) +(6x -7y) +5x
= 13x + 10y + 6x - 7y + 5x
= 24x + 3y

To simplify the expression (13x + 10y) + (6x - 7y) + 5x, you need to combine like terms.

First, remove the parentheses:
13x + 10y + 6x - 7y + 5x

Next, group the like terms together:
(13x + 6x + 5x) + (10y - 7y)

Combine the coefficients of x:
24x + (10y - 7y)

Combine the coefficients of y:
24x + 3y

So the simplified expression is 24x + 3y.

To check the answer, substitute some random values for x and y in both the original expression and the simplified expression. If the results match, it confirms that the simplification is correct.
