Step-by-step explanation:
Box 1:
180 = 124 + (5x + 11)
56 = 5x + 11
45 = 5x
x = 9
Box 2:
RT = QS
x + 9 = 2x - 5
x = 14
Box 3:
14x - 3 = 18x -19
16 = 4x
x = 4
Box 4:
180 = (9x - 8) + (7x - 4)
180 = 16x - 12
192 = 16x
x = 12
Box 5:
(6x + 34) = (12x - 8)
42 = 6x
x = 7
Box 6:
45 = 7x - 25
70 = 7x
x = 10
Box 7:
54 - x = 3x - 10
64 = 4x
x = 16
Box 8:
12x + 1 = 9x + 16
3x = 15
x = 5
Box 9:
3x + 2x - 5 = 90
5x - 5 = 90
5x = 85
x = 17
Final Code:
(9)(17) = 153
