Question 17 the sum of two numbers is 53. the larger number is 1 less than 2 times the smaller. what are the two numbers? a. 20 and 33 b. 19 and 34 c. 18 and 35 d. 17 and 36 question 19 four times a number, x, plus 3 times a number, y, equals 75. five times x minus 3 times y equals 6. find the numbers by setting up a system of linear equations and solving the system using the elimination method. a. = -7, y = 12 b. x = 6, y = 14 c. x = 8, y= 11 d. x = 9, y = 13 question 22 identify the critical points, or coordinates of the vertices of the solution region, for the system, x> 0, y> 0, x+y< 5 . a. (0, 0), (0, -5), (-5, 0) b. (0, 0), (5, 5), (-5, -5) c. (0, 0), (0, 5), (5, 0) d. (0, 0), (5, -5), (-5, 5)
