Question

150 has been divided into two parts such that twice the first part is equal to the second part. find the parts

Answer 1

let x and y be the two parts
such that x+y= 150
given that 2x=y
so x+2x= 150
3x= 150
x= 50
sub x in 2x=y
therefore y= 100
so the two parts are 50 and 100

Answer 2

Answer:

let x and be the two parts

such that x+y=150

given that 2x= 180

3x=150

x=50

sub x in 2 x= y
