4 x 7= 28
28 x 19 = 532
A Easy way to do this is to times 28 by 10. Then double it to make 560. Then subtract 28 to make 28 x 19 = 532
19 times with a remainder of 4
If: 3x+7 = 19 Then: 3x = 19-7 And: 3x = 12 So: x = 12/3 = 4
19 x 7 = 133
19
7 + 3 x 4 =7 + 12 = 19
19 times with a remainder of 4
19 times with a remainder of 4
7*4=36
If: 3x+7 = 19 Then: 3x = 19-7 And: 3x = 12 So: x = 12/3 = 4
7 x 19 = 133
19 x 7 = 133
19
7 + 3 x 4 =7 + 12 = 19
It goes into 299 , 7 times with a remainder of 19
Either 1 x 133, or 7 x 19.
76
19 * 7 = 133
