when simplified, which of the following expressions has a coefficient of -2?
4y + 6y
4y - (-6y)
4y - 6y
-4y - 6y

The correct answer would be the third one; 4y-6y

Step-by-step explanation:

The first answer, if simplified, the answer would be 10y. Which isn't the answer you are looking for.

The second answer, also has the answer of 10y, which means that isn't the one.

The third answer, when simplified, has the answer of -2y. Which, of course, would be your answer.

The fourth answer, would be -10y.

Therefor, the correct answer would be the third one.

Hope this helps!

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
