Wands - Wizard

The number promised the wizard Rhododendron that she would teach him a lot about numbers, but he must solve her riddle: My two magic wands measure 63 cm together. One is 7 cm longer. How long are her wands?

Correct answer:

a =  35 cm
b =  28 cm

Step-by-step explanation:

a+b=63  cm a=b + 7 cm  (b+7)+b=63  2b=56  b=256=28  b=28  a=b+7=28+7=35 cm
