Question

find the value of y if 2y-9=11 ​

Answer 1

Answer:

y=10

Step-by-step explanation:

2y - 9 = 11

2y = 20

Y = 10

Answer 2

Answer:

given,

2y - 9 = 11

to find:-

the value of 'y'.

$\huge\sf\underline{solution}$

2y - 9 = 11

$\sf\ implies$

2y = 11 + 9

$\sf\ since$

- 9 transposed to right side so it becomes + 9.

$\sf{implies}$ 2y = 20

$\sf{implies}$ y = $\sf\dfrac{20}{2}$

y = 10.

$\sf{since}$ value of y in "2y - 9 = 11" is 10.
