For this case we propose a system of equations:
x: Let the variable representing the length of the longer piece
y: Let the variable representing the length of the shorter piece
According to the statement data we have:
Substituting the second equation into the first we have:
Thus, the shorter piece is 30 cm.
Thus, the longer piece is 70 cm.
