Oh okay I see now thanks :) What is the value of x? \[13x2(x+4)=8x+1\]
 one year ago

nee5277 Group TitleBest ResponseYou've already chosen the best response.1
So then I would start with 11x2x+8=8x+1 right?
 one year ago

nee5277 Group TitleBest ResponseYou've already chosen the best response.1
Then add 2x to both sides? 2x+2x, 2x+8x

sorry, 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...

sorry, i did the same mistake again \(13x2(x+4)=8x+1 \\ 13x2x\large \color{red}{8}=8x+1 \\11x8=8x+1 \\ 11x8x =1+8 \\ 3x=9 \\x=3\)
