4x-7x= 13
⇒ -3x= 13
⇒ x= 13/(-3)
⇒ x= -13/3
The final answer is x= -13/3~

[Answer]
[Explanation]
4(x + 6) + 4(x - 5)
[Expand] 4(x + 6): 4x + 24
4x + 24 + 4(x - 5)
[Expand] 4(x - 5): 4x - 20
4x + 24 + 4x + 20
[Simplify] 4x + 24 + 4x - 20: 8x + 4
= 8x + 4
Answer:
n=5
Step-by-step explanation:
You can combine like terms to isolate n on one side
Add +2n to both sides; 1-2n+2n=-14+n+2n --> 1=-14+3n
Add +14 to both sides; 1+14=-14+14+3n --> 15=3n
Divide both sides by +3; 15/3 =3n/3 --> 5=n
Now you've solved for you variable; n=5
I hope this helps!
