1st number = x, 2nd number = y Translating the question mathematically it becomes: x-2 = 3y, or to make it easier: x= 3y+2, x+y= 22 Thus: (3y + 2) + y = 22  4y + 2 = 22 Move the 2 on the other side, changing its sign to negative: 4y = 22 - 2 4y = 20 Divide by 4, to obtain only y: 4y : 4 = 20 : 4 y = 5 To obtain x: x= (3*5) + 2= 15+2 = 17 Verify it: 17+5=22
