2×-3=7(×+8)ajuda gnt pfvvvv não entendo ND disso

Answer 1

$\large\sf{}2x - 3 = 7\left(x + 8\right) \\\large\sf{}2x - 3 = 7x + 56 \\ \large\sf{}2x - 3 - 7x = 56 \\ \large\sf{}2x - 7x = 56 + 3 \\ \large\sf{} - 5x = 56 + 3 \\ \large\sf{} - 5x = 59 \\ \large\sf{}x = - \dfrac{59}{9} \\ \\{\large\boxed{\boxed{  { \large \sf x = - 11,8}}}}$
