1 B 4 8 = 7
one before eight is seven (8-1 = 7)
148 = 7F
148 = 78
above is with digit, so replacing it with
148 = 7J
148 = 7D
In various radix systems:
An italicized I over the top of the = turning it into ≠ or the not equals sign.
Add "m" to for ("4," get it?). 1 from 8 = 7
It's a very boring answer:
but 148a = 7 or any variation adding a letter variable, while being a trivial addition--it does invoke a rather great meaning that is fundamental to algebra.
I think you were looking for a read aloud style puzzle
one for eight is seven one "B" for eight is seven
