How would I find the solutions to the equation |4x-6|-1=9?
| | Means the signs of the numbers are to be changed
yea the absolute value signs
-4x+6-1=9
I initially solved the problem and got x=1 and x= 1/2 but those were incorrect
alright
-4x+6-1=9 solve for x
the equation this time got me x=-1 and that's one of the correct answers, so I need to solve for the other
That is correct
the second one got me x=1 which is incorrect
Daniel's approach is fine for half the problem, but there's another half. How would I find the solutions to the equation |4x-6|-1=9? this equation can and should be broken up into two parts: Part 1 is Daniel's: +(4x-6) - 1 = 9 Part 2 is -(4x-7) -1 = 9
Solve each of these two linear equations, separately. Check each answer in the original equation.
I'm talking about the second part of the equation
@mathmale I still got an incorrect answer
it says one of the answers should be x=4, but I'm unsure how to get that answer
what was your second equation
well to solve this type of equation, you have to split it into two parts I'm not sure how I have to split it, but you gave me the first type, -4x+6-1=9
i think x is 1
I found out how to do it. 1. You have to isolate the absolute value sign 2. THEN you create the two problems 3. solve the 2 problems 4. then substitute to ensure that you have no extraneous solutions
thank you for your help @Daniel56k and @mathmale
can i see the solution
|4x-6|-1=9 add 1 to both sides to isolate the absolute value equation |4x-6|=10 then remove the signs 4x-6=10 solve this equation first 4x=16 Divide x=4 4x-6=-10 Create the next problem 4x=-4 Add six to both sides x=-1 Divide
Wow that is brilliant
