$\LARGE\tt{}7x - ( - 2x + x) + ( - 3x + 5x) \\ \LARGE\tt{}7x - ( - x) + ( - 3x + 5x) \\ \LARGE\tt{}7x - ( - x) + (2x) \\ \LARGE\tt{}7x + x + (2x) \\ \LARGE\tt{}7x + x + 2x \\ \LARGE\tt{}7x + 1x + 2x \\ \LARGE\tt{}(7 + 1 + 2)x \\ \LARGE\tt{}{\large\boxed{\boxed{  { \LARGE \tt 10x}}}}$

${\large\boxed{\boxed{  { \large \tt BONS \: \: ESTUDOS \: MEU \: ANJO \:\red{\heartsuit} }}}}$
