x = 4

Step-by-step explanation:

Given

- = ← factor the quadratic

- =

Multiply through by (x + 3)(x + 4) to clear the fractions

3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side

3x + 9 - x - 4 = x + 9

2x + 5 = x + 9 ( subtract x from both sides )

x + 5 = 9 ( subtract 5 from both sides )

x = 4
