Linear inequalities!
I need help solving the following inequality:
ABS value(7x-8) <=4x+7
+/-(7x-8) <=4x+7
7x-8 <=4x+7 -(7x-8) <=4x+7
7x-8-4x <=4x+7-4x -7x+8 <=4x+7
3x-8<=7 -7x+8-4x <=4x+7-4x
3x-8+8<=7+8 -7x-4x+8<=7
3x/3 >= 15 -11x+8<=7-8
x>=5 -11x/-11 >= -1/-11
x>=1/11
Can anyone tell me if this is right?
Also, I don't understand how to write the solution set.
Is this right? 1/11>=x>=5?
Help!
