hi, Can someone just please explain the process of how to work this inequation/absolute value question please?
I know how to work this out |2x-5| + |x+1| =8 but not these |5-x| - |3+2x| >1
@jim_thompson5910 help please :)
solve |5-x| - |3+2x| =1 and tell me what you get
here is my was of working out this question for the first question. |2x-5| + |x+1| =8
no need for the if part after the solution, you can just say the solutions are x = 4 or x = -4/3
but is the way i did this pretty much exactly the same with inequalities?
sort of...you basically solve the equation for x first that will give you a list of values which will help you set up a sign chart
which you can then use to solve the inequality
for the 3 test points i got |dw:1362726025769:dw|
