Best ResponseYou've already chosen the best response.0Okay, absolute value is never a negative. For example, 5's absolute value would be 5. Or 2's absolute value would be 2. http://www.purplemath.com/modules/absolute.htm This site should help on absolute value.

Best ResponseYou've already chosen the best response.0The first part is asking you to find the absolute value of 6x+7.

Best ResponseYou've already chosen the best response.1when doing this \[ \left 6x+7 \right=5x+2 \] either 5x+7 is positive or negative if it is zero or positive, we can drop the   (they don't do anything) so step 1: solve 6x+7 = 5x+2

phi

Best ResponseYou've already chosen the best response.1*either6x+7 is positive or negative

Best ResponseYou've already chosen the best response.1can you solve for x in 6x+7 = 5x+2 ?

Best ResponseYou've already chosen the best response.0This is what I got. 6x+7=5x+2 or 6x+7=5x2

phi

Best ResponseYou've already chosen the best response.1just 6x+7=5x+2 add 5x to both sides add 7 to both sides

phi

Best ResponseYou've already chosen the best response.1now we check to see if that works 6x+7 with x= 5 6*5+7 = 30+7 = 23 we assumed it was positive but we got a negative answer. not good but if we continue and check the other side \[ \left 6x+7 \right=5x+2 \\ 23= 5\cdot 5+2 \\ 23= 23 \text{ NO!} \]

phi

Best ResponseYou've already chosen the best response.1now let's assume 6x+7 is negative if it is negative, then 1*(6x+7) will be positive so  6x+7 is the same as 1*(6x+7) (both become positive) so let's solve \[ 1\cdot (6x+7) = 5x+2\]

phi

Best ResponseYou've already chosen the best response.1yes, and now we check this one 6x+7= 6*9/11 + 7 = 54/11 + 77/11 = 23/11 5x+2 = 5*9/11 + 22/11 = 45/11 + 22/11 = 23/11 we end up with 23/11 = 23/11 and that is not true. so there are no solutions for this problem

Best ResponseYou've already chosen the best response.0I'm supposed to graph it on a number line.

phi

Best ResponseYou've already chosen the best response.1First, are you sure we have the correct problem? can you double check?

Best ResponseYou've already chosen the best response.0All it says is to solve and graph the equation.

phi

Best ResponseYou've already chosen the best response.1yes, but are you sure it is  6x+7 = 5x+2

phi

Best ResponseYou've already chosen the best response.1in that case, there is no solution you can't graph "no solution" you can say there is none.
