x + 12 = 38. Subtract 12 from 38, getting 26. The 12 goes away because you subtracted it. x = 26, it cannot equal ten.
15x26=390

It is: (14+38)/2 = 26

x + 12 = 38. Subtract 12 from 38, getting 26. The 12 goes away because you subtracted it. x = 26, it cannot equal ten.
1/9 + 26/15 = 1 38/45

57 + 57 + 38 + 38 = 190
It is: (14+38)/2 = 26
26- 13,2 38-2, 19
There is no need to estimate: 38 - 12 = 38 - (10 + 2) = 38 - 10 - 2 = 28 - 2 = 26.
15 plus 38 is 53
26 + 26 + 26 + 26 = 4 x 26 = 104
