Answer:
[tex]x=-\frac{11}{8}[/tex]
Step-by-step explanation:
Hi there!
[tex](x - 4) - (x + 7) = 8x[/tex]
Open up the parentheses
[tex]x - 4 - x - 7 = 8x[/tex]
Combine like terms
[tex]x -x - 4 - 7 = 8x\\-4-7=8x\\-11=8x[/tex]
Divide both sides by 8 to isolate [tex]x[/tex]
[tex]-\frac{11}{8}=x[/tex]
I hope this helps!
