Question

3/8 - 1/3× (x+1)=3/26

1/3+1/2÷x=-4

Answer 1

a, 3/8-1/3 . ( x+1 )= 3/26

1/3.(x+1) =3/8-3/26= 27/104

x+1 = 27/104:1/3=81/104

x=81/104-1= (-23)/104

b. 1/3 +1/2:x = -4

1/2:x = -4 -1/3 =-13/3

x= 1/2: -13/3 

x= -3/26

Answer 2

a, 3/8 - 1/3 x ( X + 1 ) = 3/26

1/3 x ( X + 1 ) = 3/8 - 3/26

1/3 x ( X + 1 ) = 27/104

X + 1 = 27/104 : 1/3

X + 1 = 81/104

X = 81 / 104 - 1

X = -23/104

b, 1/3 + 1/2 : x = -4

1/2 : x = -4 - 1/3

1/2 : x = -13/3

x = 1/2 : -13/3

x = -3/26

Answer 3

x=-23/104

x=-3/26
