What is the solution set of the given equation?
4y - 6y + 9y = -2
A){-2/11}
B){-2/7}
C){2/7}
D){2/11}
Combine the y terms.
11y = -2
Divide both sides by 11.
I believe PsyDAG's answer is wrong.
To find the solution set of the given equation, we need to simplify and solve for y.
The given equation is:
4y - 6y + 9y = -2
First, we combine the like terms on the left side of the equation:
(4 - 6 + 9)y = -2
7y = -2
Next, we isolate y by dividing both sides of the equation by 7:
7y/7 = -2/7
y = -2/7
So, the solution to the equation is y = -2/7.
The correct answer is option B) {-2/7}.
