Question

the cost of 1 ton a/c is ₹200 more than 4 times the cost of an air cooler.Express the statement as a linear equation in two variables.MR.Vishnu donates two a/c and six air coolers to a temple.What value are shown by MR.Vishnu

Answer 1

let cost of a/c is X and cooler is y
a/q X = 4y + 200
X - 4y = 200 .............(1)
value shown by Vishnu
2x + 6y

Answer 2

Let cost of air cooler =x
then cost of a/c=4x+200
now
4x+200+x=0
5x+200=0
5x=-200
X=-200/5
x=-40
cost can't be negative so x=40
