Answer:
If you mean |5x+4|=4 real solutions: x=0 or -1.6
If you mean |5x-4|=4 real solutions: x=1.6 or x=0
If you mean |5x*4|=4 real solutions: x=0.2 or -0.2
If you mean |5x/4|=4 real solutions: x=3.2 or -3.2
Step-by-step explanation:
If you mean |5x+4|=4 real solutions:
5x+4=4 or -5x-4=4
5x=0 -5x=8
x=0 x= - 1.6
If you mean |5x-4|=4 real solutions:
5x-4=4 or -5x+4=4
5x=8 -5x=0
x=1.6 x= 0
If you mean |5x*4|=4 real solutions:
5x*4=4 or 5x*4=-4
5x=1 5x=-1
x=0.2 x= - 0.2
If you mean |5x/4|=4 real solutions:
5x/4=4 or 5x/4=-4
5x=16 5x=-16
x=3.2 x= - 3.2
