Question

16 - 2(3y + 5) = 4(y - 2)​

Answer 1

Correct question:

In 16 - 2(3y+5) = 4(y-2), find the value of y.

Required answer:

16 - 2(3y+5) = 4(y-2)

16-6y-10 = 4y-8

16-10-6y = 4y-8

6-6y = 4y-8

6+8 = 4y+6y

14 = 10y

$\frac{14}{10} = y$

1.4 = y ---> This is the value of y.

Verification:

By putting the value of y as 1.4 in the equation,

16 - 2(3×1.4+5) = 4(1.4-2)

16 - 2(4.2+5) = 4×(-0.6)

16 - 2×9.2 = -2.4

16-18.4 = -2.4

-2.4 = -2.4

Hence Verified!

Final answer:

Value of y is 1.4.
