Solve the system of equations above.
If and satisfy the equations above, find the value of the larger variable.
A frog is at the bottom of a 78 meter well. Each day he leaps 4 meters up the well. At night, while he is asleep, he slips 2 meters backwards.
How many days does it take him to escape from the well?
