Answer 2

Let's simplify the equation step by step:

1. Start with the given equation: (x - 1)(x + 2) - x(x - 3) + 5 = x + 4

2. Expand the expressions on both sides of the equation: (x^2 + 2x - x - 2) - (x^2 - 3x) + 5 = x + 4

3. Simplify within each set of parentheses: (x^2 + x - 2) - (x^2 - 3x) + 5 = x + 4

4. Distribute the negative sign in the second set of parentheses: x^2 + x - 2 - x^2 + 3x + 5 = x + 4

5. Now, simplify the equation further by combining like terms on both sides: (x^2 - x^2) + (x + 3x) + (-2 + 5) = x + 4

6. Simplify the equation: 4x + 3 = x + 4

7. Subtract 'x' from both sides to isolate 'x' terms: 4x - x + 3 = 4

8. Simplify the left side: 3x + 3 = 4

9. Subtract 3 from both sides to isolate the '3x' term: 3x = 1

10. Finally, divide by 3 to solve for 'x': x = 1/3

So, the solution to the equation is x = 1/3.
