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+7x (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.
