Question

What is the solution set of the given equation?4y - 6y + 9y = -2

Answer 1

first combine all like terms on the right side.
Now what do you get ?

Answer 2

oops...left side

Answer 3

could you just tell me the answer?

Answer 4

4y - 6y + 9y = -2
13y - 6y = -2
7y = -2
y = -2/7

check..
4(-2/7) - 6(-2/7) + 9(-2/7) = -2
-8/7 + 12/7 - 18/7 = -2
-26/7 + 12/7 = -2
- 14/7 = -2
-2 = -2 (correct)

y = -2/7
