D.

E.

Answer 1

what do you think

Answer 2

Ok I'll add some parenthesis to make it easier to understand
\((5x+6x)+(y+y+3y)+(4+6+2)\)
So add
\(5x+6x=?\\1y+1y+3y=?\\4+6+2=?\)

Answer 3

2x + 7y = -1

Answer 4

No-

Answer 5

What is 5x+6x?

Answer 6

11x

Answer 7

Yes, so now we have
\(\color{hotpink}{11x}+\color{aqua}{(y+y+3y)}+\color{lime}{(4+6+2)}\)
so now what is \(\color{aqua}{y+y+3y}\)?

Answer 8

or 1y + 1y + 3y

Answer 9

5y

Answer 10

Yes, so now add 4+6+2
\(\color{hotpink}{11x}+\color{aqua}{5y}+\color{lime}{(4+6+2)}\)

Answer 11

11x + 5y + 12

Answer 12

Yes, correct.
