Question

Help!! I have an idea of how this works but I’m not 100% sure

Answer 1

Answer:

The solution is:

x = 12

Explanation:

Given the equation:

$\frac{3}{x+3}=\frac{4}{x+8}$

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
