Answer:

The solution is:

x = 12

Step-by-step explanation:

Given the equation:


(3)/(x+3)=(4)/(x+8)

Multiply both sides of the equation by (x + 3)(x + 8)

3(x + 8) = 4(x + 3)

Remove parentheses

3x + 24 = 4x + 12

Subtract 3x from both sides

24 = 4x - 3x + 12

24 = x + 12

Subtract 12 from both sides

x = 24 - 12

= 12
