I'm here buddy,
so, let's take the value of the two bags with equal weight as x.
= x + x + (x + ) =
= 3x + =
= 3x = -
( let's take the LCM of 4 and 5 = 20
= 3x = -
= 3x =
= x = ÷
=
×
=
So, the weight of the equal bags are and the weight of the third bag ( heavy one ) is
+
=
+
=
1st bag = kg
2nd bag = kg
3rd bag = kg
Hope it helps...
If it has an equal bar under it, like this:
