Question 333582: I have to solve the equation below. It is a multiple choice question so I also listed them below.
Equation: 1/6 the absolute value of 4x-8 = 6x
Multiple choice answers: A x=8/3, x=8/5 B no solution C x=1/5 D x=-7, x=11
First I multiplied both sides by 6 to eliminate the 1/6 on the right side and made the left side 36x. Then I split the equation into 2 so that the first equation was:4x-8=36x and the second one was 4x-8=-36x. Next, on the first problem, I subtracted 4x from both sides so it was -8=32x, then I divided both sides by 32 to isolate x and got -8/32=x which I simplified into x=-1/4. On the second problem I added 8 to both sides and subtracted 36x from both sides to get 40x=8. Then, I divided both sides by 40 to isolate x and got x=8/40 or x=1/5. My question is: which answer should I choose and is my algebra correct or did I make a mistake?
Thank you!!!
