The small 2 and 1 are the 'carries' (3 x 7 = 21, and 3 x 5 = 15) The 2 is added to (4 x 7 = 28) to get 30 in 301. Then the 1 is added to (4x5 = 20) to get 21 in 215. I put the period in before 301 to try to get them to line up.

no.. x equals 11
x = ab x = 21*37 x = 777
The second would suggest that x equals the string "=3".
x = 13
x = 24
100
It is: 57*17 = 969
43/57 x 100 = 75.438596491228070175 recurring (that is, 75.438596491228070175438596491228070175...) percent.
1 x 43, 43 x 1.
1 x 57, 3 x 19.
19
1 x 43
1 x 57, 3 x 19.
250 x 57
x+27=43 x+27-27=43-27 x+0=16
2(x - 176)(x + 57) x = 176, -57
