Question

Rozwiąż równania:

(3/4) x=- (4/9)

-(4x)=2(3-x)

3(y+6)-y=2y

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

(x/6) - (1/6)=1

(1/5) *(x-3)=9-x

(2/5)*(3-x)=-2

(x/3)+1=(5/6)+(x/2)

(3/4) * (2-3x)=-6

(x+2/9) + (x-1/3)=1

(2x+3/9)+(x-1/3)=1

(2x-1/5)-(x-2/2)=0,7x

Answer 1

(3/4) x = - (4/9) / · 4/3

x = - 16/27

 

-(4x)=2(3-x)

-4x = 6 - 2x

-2x = 6

x = -3

 

3(y+6)-y=2y

3y + 18 - y = 2y

2y - 2y = - 18

0 = - 18

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

- 2/3 x = 4 / · (-3/2)

x = - 6

 

(x/6) - (1/6)=1 / ·6

x - 1 = 6

x = 7

 

(1/5) *(x-3)=9-x \ ·5

x - 3 = 45 - 5x

6x = 48

x = 8

 

(2/5)*(3-x)=-2 / · 5/2

3 - x = - 5

x = 8

 

(x/3)+1=(5/6)+(x/2) / ·6

2x + 6 = 5 + 3x

x = 1

 

(3/4) * (2-3x)=-6 / · 4/3

2 - 3x = - 8

x = 10/3

 

(x+2/9) + (x-1/3)=1

2x - 1/9 = 1

2x = 10/9

x = 5/9

 

(2x+3/9)+(x-1/3)=1

3x = 1

x = 1/3

 

(2x-1/5)-(x-2/2)=0,7x / · 10

2(2x - 1) - 5(x - 2) = 7x

4x - 2 - 5x + 10 - 7x = 0

-8x = - 8

x = 1
