19 plus 19 is 38.
(3*4 + 7)*2 = (12+7)*2 = 19*2 = 38
(12/-19) divied by (6/38) = (12/-19) x (38/6) = 456/-114 = -4
It is: 4200 plus 38 = 4238
88
19 plus 19 is 38.
38 + 19 = 57.
38/s - 7 = 12 multiply through by s 38 - 7s = 12s 38 = 19s 2 = s check 38/2 - 7 = 12 19 - 7 = 12 12 = 12 checks
50 - 12 = 38
(3*4 + 7)*2 = (12+7)*2 = 19*2 = 38
19 plus 19 is 38
-26 -12 = -38
