begin by isolating the absolute value...

Whatever in the absolute value can be negative or positive x = 3 means x can equal 3 or 3

So what does that tell you about this equation?

@trenvilla did you get the answer?

@trenvilla sorry for taking so long... however lets turn the absolute value symbols into parantheses.

ok 9(9 – 8x) = 2x + 3

8172x=2x+3 (Personally, I hate writing +)
 one year ago

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

MathLegendBest ResponseYou've already chosen the best response.0
8172x=2x+3 lets look at our 'x' values first.

MathLegendBest ResponseYou've already chosen the best response.0
Is 72 a negative or a positive?
 one year ago

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

MathLegendBest ResponseYou've already chosen the best response.0
So in this case it is negative.
 one year ago

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

trenvillaBest ResponseYou've already chosen the best response.0
wont u have to make it 70
 one year ago

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

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

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

Can you simplify this by combing the 81 and 3?
 one year ago

MathLegendBest ResponseYou've already chosen the best response.0
So what do you get?
 one year ago

MathLegendBest ResponseYou've already chosen the best response.0
You 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
 one year ago

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

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

MathLegendBest ResponseYou've already chosen the best response.0
simplify that and what do you get?
 one year ago

MathLegendBest ResponseYou've already chosen the best response.0
Simplify as a fraction
 one year ago

MathLegendBest ResponseYou've already chosen the best response.0
That is right as a decimal but you would ideally simplify to a fraction
 one year ago

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

MathLegendBest ResponseYou've already chosen the best response.0
That is your answer
