Question

1) X+1/3 - x-1/3 = 5/2 + x

2) 2(x-1)/3 - 3(x+1) = - (x+2)/6

Gente ajudaaa

Answer 1

Resposta:

1)

Se for assim ==>1) x+1/3 - x-1/3 = 5/2 + x

x+1/3 - x-1/3 = 5/2 + x

1/3 -1/3 = 5/2 + x

0= 5/2 + x  ==> x=-5/2

2)

2(x-1)/3 - 3(x+1) = - (x+2)/6

multiplique tudo por 6

6*2(x-1)/3 -6* 3(x+1) = -6* (x+2)/6

4(x-1) -18(x+1) = - (x+2)

4x-4-18x-18=-x-2

-14x-22=-x-2

-14x +x =22-2

-13x=20

13x=-20

x=-20/13

x=-20/13
