Answer:
10
Explanation:
Original expression:
\((4y+8x+6)+25+(4x+6y+7)\)
Let's simplify it step-by-step:
\(4y+8x+6+25+4x+6y+7\) (removing the parentheses)
\(4y+12x+6+25+6y+7\) (adding together similar terms in x)
\(10y+12x+6+25+7\) (adding together similar terms in y)
\(10y+12x+38\) (adding together similar terms with no variable)
So, from the final expression, we see that the coefficient for y is 10.
