19. Max and Sasha exercise a total of 20 hours each week. Max exercises(15 hours less than 4 times the number of hours Sasha exercises. The system x +y = 20 x - 4y =-15 situation, where x represents the number of hours Max exercises and y represents the number of hours Sasha exercises. How many hours do Max of equations represents this and Sasha exercise per week? 20. The sum of the digits in a two-digit number is 12. The digit in the tens place is(2 more than the digit in the ones place. The system of linear x+y = 12 equations represents this situation, x- y = 2 where x is the digit in the tens place and y is the digit in the ones place. Solve the system to find the two-digit number.
