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
