When two different liquids are mixed together and the observation indicates an exothermic reaction takes place, the observation can be that heat is evolved after contact and the container's temperature becomes higher. This is because heat is released in this type of rxn.
Answer:
12 - x = 20 - 5x
Add 5x on both sides,
12 - x + 5x = 20 - 5x
12 + 4x = 20
Subtract 12 on both sides,
12 - 12 + 4x = 20 - 12
4x = 8
Divide 4 on both sides,
4x / 4 = 8 / 4
x = 2
Hence proved.
