Answer:

[tex]x=-8.5[/tex]  or  [tex]x=-\frac{17}{2}[/tex]

Step-by-step explanation:

[tex]-4x+8=42[/tex]

Subtract 8 from both sides.

[tex]-4x=42-8[/tex]

Subtract 8 from 42 to get 34.

[tex]-4x=34[/tex]

Divide both sides by −4

[tex]x=\frac{34}{-4}[/tex]

Reduce the fraction

[tex]\frac{34}{-4}=-\frac{17}{2}[/tex]

[tex]\frac{34}{-4}=-8.5[/tex]

Hope that wasn't confusing!

Hope this helps! o(〃^▽^〃)o
