Question

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

Answer 1

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

Answer 2

Answer:

$y=-\frac{2}{7}$

Step-by-step explanation:

Given: $4y-6y+9y=-2$

To find: The solution set of the equation.

Solution:

We have, $4y-6y+9y=-2$ , and we need to find the solution set.

Now, we know that a solution set is any value of a variable in an equation which satisfies the equation. So, we need to find the value of variable, y in the given equation.

So, we have

$4y-6y+9y=-2$

$\implies 13y-6y=-2$

$\implies 7y=-2$

$y=-\frac{2}{7}$

Hence, the solution set of the equation is $y=-\frac{2}{7}$
