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
ok so (81+-72)=2x+3
is that right
81-72x=2x+3 (Personally, I hate writing +-)
So combine like terms... if I were you I would keep my 'x' positive.
ok so 84-74
81-72x=2x+3 lets look at our 'x' values first.
Is 72 a negative or a positive?
No, in this equation it has a minus sign in front of it right?
So in this case it is negative.
o ok
So how can we combine -72x and the positive 2x to keep the answer POSITIVE?
i dont no how
wont u have to make it -70
No, you can either make this positive 74 OR -74
Remember... if we had -72x = 2x If we combine we need the 'x' variable to be on one side of the equal sign
Okay, so lets add -72x to the positive 2x
81 = 74x + 3
Can you simplify this by combing the 81 and 3?
So what do you get?
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
Which would keep your 'x' on one side and the regular number on the other side
o ya so 78+74x
78 = 74x
ya i ment =
then you divide and you get \[\frac{ 78 }{ 74}\]
simplify that and what do you get?
ia thtat right
Simplify as a fraction
That is right as a decimal but you would ideally simplify to a fraction
1 4 over 74
Okay we have 78/74
So if I were you I would divide the numerator by 2 then the denominator by 2
That is your answer
thank you for all your help
