Question

Resolva a proporção 4/9=x+1/18

Answer 1

$\large\sf{} \dfrac{4}{9} = \dfrac{x + 1}{18} \\ \\ \large\sf{}4 \times 18 = 9\left(x + 1\right) \\ \\ \large\sf{}72 =9 \left(x + 1\right) \\ \\ \large\sf{}8 = x + 1 \\ \large\sf{} - x = 1 - 8 \\\large\sf{} - x = - 7 \\ \large\sf{} {\large\boxed{\boxed{  { \large \sf x = 7}}}}$
