Okay, so after a bit of research the original equation seems to be:
1/7=3/4x-1
To solve, we need to isolate x on one side. Let's by adding 1 to both sides (and thus eliminate -1):
1/7+1=3/4x
8/7=3/4x
Let's now multiply by 4 both sides (to eliminate the denominator 4):
4*8/7=3x
32/7=3x
Let's now divide both sides by 3 (to eliminate the 3 from 3x):
32/(7*3)=x
32/21=x
We conclude that x=32/21 or 1 11/21
