Answer:
x=4
Step-by-step explanation:
1. isolate the variable by subtracting 7 on both sides: 4x=23-7
2. simplify: 4x=16
3. divide both sides by 4: x=16/4
4. simplify: x=4

Answer:
Step-by-step explanation:
- (x³ + 1) / (x - 1) =
- (x³ - 1 + 2) / (x - 1) =
- (x³ - 1)/(x - 1) + 2/(x - 1) =
- (x - 1)(x² + x + 1)/(x - 1) + 2/(x - 1) =
- x² + x + 1 + 2/(x - 1)
