Best ResponseYou've already chosen the best response.0Whatever in the absolute value can be negative or positive x = 3 means x can equal 3 or 3

Best ResponseYou've already chosen the best response.0So what does that tell you about this equation?

Best ResponseYou've already chosen the best response.0@trenvilla sorry for taking so long... however lets turn the absolute value symbols into parantheses.

Best ResponseYou've already chosen the best response.0ok 9(9 – 8x) = 2x + 3

Best ResponseYou've already chosen the best response.08172x=2x+3 (Personally, I hate writing +)

Best ResponseYou've already chosen the best response.0So combine like terms... if I were you I would keep my 'x' positive.

Best ResponseYou've already chosen the best response.08172x=2x+3 lets look at our 'x' values first.

Best ResponseYou've already chosen the best response.0Is 72 a negative or a positive?

MathLegend

Best ResponseYou've already chosen the best response.0No, in this equation it has a minus sign in front of it right?

MathLegend

Best ResponseYou've already chosen the best response.0So in this case it is negative.

MathLegend

Best ResponseYou've already chosen the best response.0So how can we combine 72x and the positive 2x to keep the answer POSITIVE?

Best ResponseYou've already chosen the best response.0wont u have to make it 70

MathLegend

Best ResponseYou've already chosen the best response.0No, you can either make this positive 74 OR 74

MathLegend

Best ResponseYou've already chosen the best response.0Remember... if we had 72x = 2x If we combine we need the 'x' variable to be on one side of the equal sign

MathLegend

Best ResponseYou've already chosen the best response.0Okay, so lets add 72x to the positive 2x

Best ResponseYou've already chosen the best response.0Can you simplify this by combing the 81 and 3?

MathLegend
 3 years ago
Best ResponseYou've already chosen the best response.0You had a 81 and a positive 3 on the other side of the equal sign to get the 3 to the opposite side you want to subtract 3

MathLegend

Best ResponseYou've already chosen the best response.0Which would keep your 'x' on one side and the regular number on the other side

MathLegend

Best ResponseYou've already chosen the best response.0then you divide and you get \[\frac{ 78 }{ 74}\]

MathLegend

Best ResponseYou've already chosen the best response.0simplify that and what do you get?

MathLegend

Best ResponseYou've already chosen the best response.0Simplify as a fraction

MathLegend
 3 years ago
Best ResponseYou've already chosen the best response.0That is right as a decimal but you would ideally simplify to a fraction

MathLegend

Best ResponseYou've already chosen the best response.0So if I were you I would divide the numerator by 2 then the denominator by 2
