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

Correct answer:

a =  60 cm
b =  50 cm

Step-by-step explanation:

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
