Best ResponseYou've already chosen the best response.1Oh okay I see now thanks :) What is the value of x? \[13x2(x+4)=8x+1\]

nee5277

Best ResponseYou've already chosen the best response.1sorry, got disconnected \(13x2(x+4)=8x+1 \\ 13x2x\large \color{red}{+8}=8x+1 \\11x+8=8x+1 \\ 11x8x =17 \\ 3x=6 \\x=....?\) ask if there is any doubt in any step...
