Answer:
-5
The Problem:
If [tex]-2x+5x+3=12[/tex], then the value of [tex]x-8[/tex] is ?
Step-by-step explanation:
Let's solve this for x:
[tex]-2x+5x+3=12[/tex]
Combine like terms:
[tex]3x+3=12[/tex]
Subtract 3 on both sides:
[tex]3x=12-3[/tex]
Simplify:
[tex]3x=9[/tex]
Divide both sides by 3:
[tex]x=\frac{9}{3}[/tex]
Simplify:
[tex]x=3[/tex]
So if [tex]x=3[/tex] then [tex]x-8=3-8=-5[/tex].
Answer:
-5
Step-by-step explanation:
If you combine the like terms you would get 3x + 3= 12. Where u subtract 3 on each side, you would get 3x=9 and when you divide 3 on each side you would get x=3. To answer the problem, 3-8 would be -5.
