Question 405186
 solve and show the answer in interval notation: 
3x-4<8 and 4x-1<13 
i got: 
3x-4<8 
+4 +4 
3x<12 
x<4 

4x-1<13
+1 +1
4x<14
x< 7/2 
but professor marked it wrong.

The work you are showing is correct.
The problem involes "AND" so the 
interval values must satisfy both
of the inequalities.
---
For x to be <4 AND <7/2 the values
would have to be <7/2.
---
Interval Solution: (-inf,7/2)
