5x + 15y = 1200. x. | y
___________
105 | 45
30. | 100
60. | 60
5(x) + 15y = 1200. 5(x) + 15y = 1200. 5(x) + 15y = 1200.
5(x) + 15(45) = 1200. 5(30) + 15y = 1200. 5(x) + 15(60) = 1200
5x + 675= 1200. 150 + 15y = 1200. 5x + 900 = 1200
5x = 1200 - 675 15y = 1200 - 150. 5x = 1200-900
5x = 525 15y = 1050. 5x = 300
x= 525÷5. y= 1050÷15. x = 300÷5
x= 105. y = 100 x = 60
