Question

Construct word problem on simultenious linear equation in two variables so that the value of one of variables will be 10 (pesons ,rupees,metres,years,etc.) & Solve it​

Answer 1

example: The sum of ages of Ajay and Vijay is 11. Ajay is elder than Vijay by 9 years. find there present ages.

let age of Ajay be x and age of Vijay be y

according to the first condition
x+y=11.........(1)

according to second condition
x=y+9,
x-y=9..........(2)

adding eqn ( 1 )and (2)
x+y=11
x-y=9
---------
2x = 20
x=10

put x=10 in equation (1)
x+y=11
10+y=11
y=11-10
y=1
hence age of Ajay is 10 years
and age of Vijay is 1 year
