The answer is -60. this is because the signs implemented in front of numbers give it a sort pattern .
when there are two additions the last number after the positive sign will give a positive number 1 greater than the initial number for example + 5 + 6. Answer afterward will be + 7 and for negative sign eg: - 7 - 8 in the question will give the answer -8 the same number after a negative (-) sign .
Hope this helps

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...
