Let their ages be x and y: x+y = 51 => y = 51-x xy = 648 x(51-x) = 648 51x-x2-648 = 0 x2-51x+648 = 0 (x-24)(x-27) = 0 x = 24 or x = 27 So their ages were 24 and 27 Check: 24+27 = 51 and 24*27 = 648
1 x 346, 2 x 173.
72 x 9 = 648
40(x) + 7(2x)=648 40x + 14x = 648 54x = 648 x = 12 ■
1.2346
648 = ?%*900 648 = x/100*900 648 = 9x x = 648/9 x = 72
46 x 346 = 15916
346 x 2,656= 918,976
7 times what equals 346

Let their ages be x and y: x+y = 51 => y = 51-x xy = 648 x(51-x) = 648 51x-x2-648 = 0 x2-51x+648 = 0 (x-24)(x-27) = 0 x = 24 or x = 27 So their ages were 24 and 27 Check: 24+27 = 51 and 24*27 = 648
1 x 346, 2 x 173.
648 = 2 x 2 x 2 x 3 x 3 x 3 x 3
346 = (3 x 100) + (4 x 10) + (6 x 1)
346 = (3 x 100) + (4 x 10) + (6 x 1)
346 x 45 = 15570
648 = 23 x 34
