Answer 2

Answer:

x = 4

Step-by-step explanation:

Given : ${\sf{{\dfrac{5}{15}} = {\dfrac{x}{x + 8}}}}$

• Simplifying the terms.

$\implies{\sf{ {\dfrac{1}{3}} = {\dfrac{x}{x + 8}}}}$

• Cross - multiplication.

$\implies{\sf{ (1)(x + 8) = (3)(x)}}$

$\implies{\sf{(1)(x) + (1)(8) = (3)(x)}}$

$\implies{\sf{x + 8 = 3x}}$

• Transposing the terms.

$\implies{\sf{3x - x = 8}}$

$\implies{\sf{2x = 8}}$

$\implies{\sf{x = {\dfrac{8}{2}}}}$

$\implies{\boxed{\boxed{\sf{x = 4}}}}$
