Question

What's the answer too |3x-7|=12

Answer 1

First, suppose 3x - 7 is greater then 0 and solve 3x - 7 = 12
Then, suppose it is not and solve -(3x - 7) = 12, that is 7 - 3x = 12

Answer 2

5/3

Answer 3

You're wrong though. :| @finiteok

Answer 4

5/3 and 19/3

Answer 5

@mathway I am not wrong but thank you

Answer 6

Do what @Andrea_Grossoni said. Solve for x on both equations.

Answer 7

X is 19/3 and 5/3

Answer 8

Is what Andrea said the final answer?

Answer 9

No. Solve for x in:
3x-7=12

and

-(3x-7)=12

Answer 10

@finiteok , the answer 5/3 is wrong, put 5/3 instead of x in the equation and you'll see
The answer is -5/3, and of course 19/3

Answer 11

I wish you were, but you're not. Try again. @finiteok ((but you got one correct though))
