how did you get 5 ?? and you can check your answer by plugging 5 into x if you get both side equal then your answer is PERFECT!

OpenStudy (anonymous):

Yeah that's what I initially did. I plugged it in.

Nnesha (nnesha):

\[\huge\rm 6(\color{red}{x}+4) = 3(4\color{red}{x} -2)\] \[\rm\color{red}x = 5\] replace x by 5 what do you get at right and left side ?

OpenStudy (anonymous):

I was given a few answers to pick from and plugged them all in but I wouldn't know how to do it it I was given choices.

OpenStudy (anonymous):

on the left I get 9 and on the right I get 18?

Nnesha (nnesha):

nope try again

OpenStudy (anonymous):

Oh wait (I'm trying to think back how it was explained and I got it right yesterday)

OpenStudy (anonymous):

You are correct in x=5

OpenStudy (anonymous):

Okay my notes: this is how I did it yesterday. 6x + 24 = 12x - 6 6x + 24 = 12x - 6 6x + 24 - 12x = 12x - 6 - 12x -6x + 24 = -6 -6x + 24 - 24 = -6 - 24 -6x = -30 then divide both sides by -6 so...

OpenStudy (anonymous):

-6x/-6 = -30/-6 which = 5 Idk... if that's right but it makes sense ish...

Nnesha (nnesha):

yep that's right :-) so you can check your answer by urself :-) replace x by 5 \[\huge\rm 6(\color{red}{5}+4) = 3(4\color{red}{(5)} -2)\] \[\rm\color{red}x = 5\]

Nnesha (nnesha):

solve left and right side

OpenStudy (anonymous):

I'm just getting 54 though.

Nnesha (nnesha):

yes left side 54 and right side 54 \[\huge\rm 6(\color{red}{5}+4) = 3(4\color{red}{(5)} -2)\] \[\huge\rm 6 (9) = 3(20-2)\] \[54 = 3(18)\] \[\huge\rm 54 = 54\] both side equal that's mean your answer is right :-)if both side are not equal then answer is wrong :-) gO_Od work!

OpenStudy (anonymous):

Oh I see why do I have to go back to the (20-2)? It makes sense though, thanks.

www.mathpapa.com that should help

Nnesha (nnesha):

i did step by step you have to distribute 5 by 4 \[\huge\rm 6(\color{red}{5}+4) = 3(4\color{red}{(5)} -2)\]|dw:1429404916797:dw| \[\huge\rm 6 (9) = 3(20-2)\] \[54 = 3(18)\] \[\huge\rm 54 = 54\] both side equal that's mean your answer is right :-)if both side are not equal then answer is wrong :-) gO_Od work!
