Prices prices

The meter of the textille was reduced by CZK 42, so 4 meters of the new price was 20 CZK cheaper than 3 meters of the original price. What was the original and new price of the textille?

Correct result:

a =  148
b =  106


a = 42 + b
4b = 3a - 20

a = 42 + b
4•b = 3•a - 20

a-b = 42
3a-4b = 20

a = 148
b = 106
