Answer:
Step-by-step explanation:
We know that:
We observe the denominator of the first expression is same as the product of the denominators of the second expression.
Compare the numerators and solve for b:
- 5(x - 1) - 4(x - b) = x + 3
- 5x - 5 - 4x + 4b = x + 3
- x - 5 + 4b = x + 3
- 4b - 5 = 3
- 4b = 8
- b = 2
