Answer:
x = - 7
Step-by-step explanation:
1) Add 8 to both sides.
-8x-8=-5x+13
-8x - 8 + 8 = -5x + 13 + 8
2) Simplify
- Add the numbers
-8x - 8 + 8 = -5x + 13 + 8
-8x = -5x + 13 + 8
- Add the numbers
-8x = -5x + 13 + 8
-8x = -5x + 21
3) Simplify
- Combine like terms
-8x + 5x = -5x + 21 + 5x
-3x = -5x + 21 + 5x
- Combine like terms
-3x = -5x + 21 + 5x
-3x = 21
4) Divide both sides by the same factor
-3x + 21
-3x/-3 = 21/-3
6) Simplify
- Cancel terms that are in the numerator and denominator
-3x/-3 = 21/-3
x = 21/-3
- Divide the numbers
x = 21/-3
x = -7
The answer would be x = -7.
