Calculate the surface of a soccer field, but its measurements are unknown. To determine what the measurements of the field are, the maintenance operator is consulted who indicates that the relationship between width and length minus 30 meters is equal to a medium. Likewise, the sum of the length plus the value of the width is 150 meters.
