Question

 perguntas da minha prova pergunta b  4x - 5x + 1 = 0   c -x + 14x - 33 = 0  d - 2x + x + 1 = o  e 18x - 3x - 1 = 0 

Answer 1

b) 4x - 5x + 1 = 0
- x = - 1 (-1)
x = 1

c) - x + 14x - 33 = 0
13x = 33
x = 33/13

d) - 2x + x + 1 =0
- x = - 1 (-1)
x = 1

e) 18x - 3x - 1 = 0
15x = 1
x = 1/15

Answer 2

B)RESOLVENDO
4X-5X=-1
-X=-1
X=-1/-1
X=1

C)-X+14X=33
13X=33
X=33/13
D)-2X+X=-1
-X=-1
X=-1/-1
X=1

E) 18X-3X=1
15X=1
X=1/15
