Question

Which of the following expressions is equivalent

to 7x + 9y - 6 - 3y + 4?
A 7x + 4y
B 11xy
C 7x + 6y - 2
D. 7X+4​

Answer 1

The expression simplifies to 7x + 6y - 2 by combining like terms, making answer choice C the equivalent expression.

Step-by-step explanation:

The expression 7x + 9y - 6 - 3y + 4 can be simplified by combining like terms. First, combine the 'y' terms (9y - 3y) to get 6y. Then, combine the constant terms (-6 + 4) to get -2. After combining these terms, the expression simplifies to 7x + 6y - 2, which is answer choice C.

Answer 2

C

Step-by-step explanation:

All that is needed to do is combine like terms. The sign in front of each term stays with it. Like +9y-3y=6y, 7x would isolate itself since it has not other term to follow. And -6+4=-2. This would all lead to C. 7x+6y-2.
