Question

find the value of y
y/14 - 1/2 = 1/14​

Answer 1

Answer:

$\frac{y}{14} - \frac{1}{2} = \frac{1}{14} \\ \\ = > \frac{y - 7}{14} = \frac{1}{14} \\ \\ = > 14(y - 7) = 14 \\ \\ = > 14y - 98 = 14 \\ \\ = > 14y = 14 + 98 \\ \\ = > 14y = 112 \\ \\ = > y = \frac{112}{14} \\ \\ = > y = 8$

Answer 2

Given :

• y/14 - 1/2 = 1/14

To find :

• the value of y

Solution :

y/14 - 1/2 = 1/14

y - 7/14 = 1/14

14(y - 7) = 14(1)

14y - 98 = 14

14y = 14 + 98

14y = 112

y = 112/14

y = 8

∴ Value of y is 8
