Answer:
[tex]x=-2/5\text{ or } x=-4/5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]9-4|3+5x|=5[/tex]
First, subtract 9 from both sides:
[tex]-4|3+5x|=-4[/tex]
Divide both sides by -4:
[tex]|3+5x|=1[/tex]
Definition of Absolute Value:
[tex]3+5x=1\text{ or } 3+5x=-1[/tex]
Subtract 3 from both sides:
[tex]5x=-2\text{ or } 5x=-4[/tex]
Divide both sides by 5:
[tex]x=-2/5\text{ or } x=-4/5[/tex]
And we're done!
Answer:
x = -2/5 x = -4/5
Step-by-step explanation:
9-4|3+5x|=5
Subtract 9 from each side
9-9-4|3+5x|=5-9
-4|3+5x|=-4
Divide by -4
-4/-4 |3+5x|=-4/-4
|3+5x|=1
The solution to an absolute value is positive and negative
3+5x =1 3+5x = -1
Subtract 3 from each side
5x = 1-3 5x = -1-3
5x = -2 5x = -4
Divide by 5
5x/5 = -2/5 5x/5 = -4/5
x = -2/5 x = -4/5
