Question

3(x-7)=2(x+1)-16 quanto ?

Answer 1

3(x-7)=2(x+1)-16

3x-21=2x+2-16

3x-2x=21+2-16

x=7

Answer 2

$\large\bm{3\left(x - 7\right) = 2\left(x + 1\right) - 16} \\\\ \large\bm{}3x - 21 = 2\left(x + 1\right) - 16 \\\\ \large\bm{}3x - 21 = 2x + 2 - 16 \\\\ \large\bm{}3x - 21 = 2x - 14 \\\\ \large\bm{}3x - 21 - 2x = - 14 \\\\ \large\bm{}3x - 2x = - 14 + 21 \\\\ \large\bm{}x = - 14 + 21 \\\\ \bm{\large\boxed{\boxed{  { \large \bm{ x = 7 }}}}}$

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