ME AJUDA PLISSO S2

Answer 1

E) 5x -5 +x = 9+x => 6x - 5 = 9 +x => 6x - x = 9 + 5 => 5x = 14 => x = 14/5

F) 7x - 4 - x = -2 x + 8 - 3x => 6x - 4 = - 5x + 8 => 6x + 5x = 8 + 4 => 11x = 12
=> x = 12/11 

Answer 2

e) 5x - 5 + x = 9 + x
5x + x - x = 9 + 5
5x = 14
x = 14/5 = 2,8

f) 7x - 4 - x = - 2x + 8 - 3x
7x + 2x + 3x - x = 8 + 4
11x = 12
x = 12/11
