12 divided by 4y+6 = 2/7

Mila [183]

Answer:

The correct answer is y = 9

Step-by-step explanation:

It is given that,

12/(4y + 6) = 2/7

To find the value of y

12/(4y + 6) = 2/7

By cross multiplying,

12 * 7 = 2 * (4y + 6 )

84 = 8y + 12

8y + 12 = 84

8y = 84 - 12

8y = 72

y = 72/8 = 9

y = 9

Therefore by solving the given expression we get the value of y = 9
