Divide

Divide substance 110 cm long to two parts so that it first part is 10 cm longer than the second part and one part will be 10 times longer than the second portion. How long the parts will be?

Correct answer:

a =  60 cm
b =  50 cm

Step-by-step explanation:


a+b=110
a = 10+b

a+b = 110
a-b = 10

Row 2 - Row 1 → Row 2
a+b = 110
-2b = -100


b = -100/-2 = 50
a = 110-b = 110-50 = 60

a = 60
b = 50
