Question

Separate the number 41 in ro two u parts so that the first number is 8 more than twice the second number.

Answer 1

x + y = 41 (1)

x = 2y + 8 (2)

From first equation:

x = 41 - y (3)

Equaling 2 and 3:

2y + 8 = 41 - y

3y = 33

y = 11

Finally we replace x on 1, as follows:

x + 11 = 41

x = 41 - 11

x = 30
