I really do hope you know your laws of indices coz if u don't u may not understand this.
Step-by-step explanation:
firstly...lets convert that 27 in powers of 3
= 3^3
3^2x-1 =1 /3^3(x-3)
NB: in indices, I/a =a^-1
3^2x-1= 3^-1*3(x-3)
3^2x-1=3^-3(x-3)
cancel out the 3 from both sides leaving the powers behind
2x-1=-3x+9
collect like terms.
2x+3x=9+1
5x=10
therfore x=2
that's it
hope this was helpful
