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

So then I would start with 11x2x+8=8x+1 right?

nee5277Best 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 \(13x2(x+4)=8x+1 \\ 13x2x\large \color{red}{8}=8x+1 \\11x8=8x+1 \\ 11x8x =1+8 \\ 3x=9 \\x=3\)

Oh oh I see sorry lol it looked like a 6 for a minute. thanks. How about Debbie solved a linear equation 3(x+4)2=16 where did she make an error? Line 1: 3(x+4)2=16 Line 2: 3(x+4)=18 Line 3: 3x+4=18 Line 4: 3x=14 Line 5: \[4\frac{ 2}{ 3 }\]
