Find an expression which represents the difference when (6x-3y) is subtracted from (9x+2y) in simplest terms.
Alex73 [517]

Answer:

3x+5y

Step-by-step explanation:

Subtract (6x-3y) from (9x+2y):

(9x+2y)-(6x-3y)

This can also be seen as:

(9x+2y)-1(6x-3y)

Distribute the -1 to (6x-3y):

(9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y

Simplify the parentheses:

9x+2y-6x+3y

Group like terms:

(9x-6x)+(2y+3y)

Combine:

3x+5y

This expression can't be further simplified. Therefore, 3x+5y is the answer.

:Done
