Question

If sarthak and sakshi's age is x years and y years resp ,then sum of their ages is 25 is given by the equation. ​

Answer 1

Answer:

this is the answer nark me as brainlest

Answer 2

x+y=25....(i)

Next, we are given that Sarthak's age is less by 8 than double the age of Sakshi. Double the age of Sakshi is represented by 2y. So, the given statement can be written as an equation in the following manner,

x=2y−8....(ii)

from equation (ii) in equation (i). We get the following equation,

2y−8+y=25

3y−8=25⇒3y=25+8⇒3y=33∴y=11

Now, substituting this value of y in equation (ii), we get

x=2×11−8⇒x=22−8∴

x=14

x=14 y=11

Answer 3

x+y=25....(i)

Next, we are given that Sarthak's age is less by 8 than double the age of Sakshi. Double the age of Sakshi is represented by 2y. So, the given statement can be written as an equation in the following manner,

x=2y−8....(ii)

from equation (ii) in equation (i). We get the following equation,

2y−8+y=25

3y−8=25⇒3y=25+8⇒3y=33∴y=11

Now, substituting this value of y in equation (ii), we get

x=2×11−8⇒x=22−8∴

x=14

x=14 y=11
