0,5 + x : 0,125 = 10,35

x : 0,125 = 10,35 - 0,5

x : 0,125 = 9,85

x = 9,85 × 0,125

x = 1,23125

x : 0,5 + x × 0,5 = 0,75

x × 1 + x × 0,5 = 0,75

x × (1 + 0,5) = 0,75

x × 1,5 = 0,75

x = 0,75 : 1,5

x = 0,5

\(x:0,5+x\times0,5=0,75\)'

\(\Rightarrow x:\frac{5}{10}+x\times\frac{5}{10}=\frac{3}{4}\)

\(\Rightarrow\frac{10x}{5}+\frac{5x}{10}=\frac{3}{4}\)

\(\Rightarrow2x+\frac{5x}{10}=\frac{3}{4}\)

\(\Rightarrow\frac{40x}{20}+\frac{10x}{20}=\frac{15}{20}\)

107 + ( 210 + x ) = 317

210 + x = 317 - 107

210 + x = 210

x = 210 - 210

x = 0

2x + (0,5 + 25%) = 0,75

2x + (0,5 + 0,25) = 0,75

2x + 0,75 = 0,75

2x = 0,75 - 0,75

2x = 0

x = 0 : 2

x = 0

a, 107 + ( 210 - x ) = 317

210 - x = 317 - 107

210 - x = 210

x = 210 - 210

x = 0

Vậy x = 0

b, 2x + ( 0,5 + 25% ) = 0,75

2x + 0,75 = 0,75

2x = 0,75 - 0,75

2x = 0

x = 0

Vậy x = 0

c, 4221 : ( x - 16 ) = 21

x - 16 = 4221 : 21

x - 16 = 201

x = 201 + 16

x = 217

Vậy x = 217

d, 156 - ( x + 61 ) = 21

x + 61 = 156 - 21

x + 61 = 135

x = 135 - 61

x = 74

Vậy x = 74

e, ( 235 - x ) - 81 = 54

235 - x = 54 + 81

235 - x = 135

x = 235 - 135

x = 100

Vậy x = 100

f, 50% + 0,75. x = 0,5

0,75. x = 0,5 - 50%

0,75. x = 0

x = 0

Vậy x = 0

X*(1/3-0.5)=0.75

X*-1/6=0.75

X=0.75/(-1/6)

X=-9/2

1/3*x-1/2*x=0,75.

(1/3-1/2)*x=3/4.

-1/6*x=3/4.

x=3/4:(-1/6).

x=-9/2.

Vậy x=-9/2.
