Today:
Linda is X yrs. old.
Sally is 4x yrs. old.
Ten yrs. from today:
Linda will be x+10 yrs. old.
Sally will be 4x+10 yrs. old.
(x+10) + (4x+10) = 75.
X = ?
4x = ?
Linda is X yrs. old.
Sally is 4x yrs. old.
Ten yrs. from today:
Linda will be x+10 yrs. old.
Sally will be 4x+10 yrs. old.
(x+10) + (4x+10) = 75.
X = ?
