Answer 1

x=9

Explicação passo-a-passo:

Answer 2

$\large\bm{13x - 8\left(2x - 1\right) + 7 = 17x + 5\left(2 - x\right) - 14x - 4} \\\\ \large\bm{}13x - 16x + 8 + 7 = 17x + 5\left(2 - x\right) - 14x - 4 \\\ \large\bm{}13x - 16x + 8 + 7 = 17x + 10 - 5x - 14x - 4 \\\\ \large\bm{} - 3 x + 8 + 7 = 17x + 10 - 5x - 14x - 4 \\ \large\bm{} - 3x + 15 = 17x + 10 - 5x - 14x - 4 \\ \large\bm{} - 3x + 15 = - 2x + 10 - 4 \\ \large\bm{} - 3x + 15 = - 2x + 6 \\ \large\bm{} - 3x + 15 + 2x = 6 \\ \large\bm{} - 3x + 2x = 6 - 15 \\\large\bm{} - x = 6 - 15 \\ \large\bm{} - x = - 9 \\ \bm{\large\boxed{\boxed{  { \large \bm{ x = 9 }}}}}$

${\large\boxed{\boxed{  { \large \bm{ Bons~Estudos} }}}}$
