Question

The total mass of Fatin and Hanim is 68 kg. Fatin is 6 kg lighter than Hanim. Find their respective masses.​

Answer 1

Hatim=37kg, Fatin=31

Explanation:

Hatim=x, Fatin=x-x

x+x-6=68

add 6 to both sides

x+x=74

2x=74

divide both sides by 2

x=37

put in 37 fo the values determined earlier

Hatim=37, Fatin=37-6

Hatim=37, Fatin=31

check by plugging in the values

37+31=68 (or 37+37-6=68, either one works)
