Question

The weight of Manish is 3kg less than twice the age of bhavesh.if their total weight is 78 kg form the equation to find the weight of bhavesh

Answer 1

let age of bhavesh be x kg
then weight of manish is= (2x-3)kg
total weight is 78 kg
therefore, x+(2x-3)=78

Answer 2

Let the wieght of bhavesh be x.
Therefore,manish wieght becomes 2x-3.
total wieght=78kg
2x-3+x=78
2x+x=78+3
3x=81
x=81/3
x=27
bhavesh wieght is 27kg.
manish weight  is 51kg.
