Question

Construct a word problem on simultaneous linear equations in two variables
(on age, rupees, metres, speed, etc.), so that the value of one variable will be 18.​

Answer 1

let the no.be x and y.

the sum of no.is 38

hence,x+y=38....(1)

the difference between them is 2

x-y =2.....(2)

Add 1 and 2

so 2x=36

x=18..

and 18+y=38

=20

hence ,the no.are 18 and 20
