Question

Rozwiążcie mi proszę to zadanie najlepiej do dzisiaj pilne ;))

Wyprosc wyrażenia:

3x+7-5x-11=

2(x-7+3x)=

3x-2(x-1)=

-5(x-7)+3x-2=

2a+3b=7a-11=

1/2(4x-10)+3x-2=

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

-(x+3)-(1x+4)=

-(x+3)-(2x+4)+

5(-x-7)-2(x+3)=

(5x-10)/(-1/3)=

Answer 1

1) = -2x-4

2) = 2x-14+6x= 8x-14

3) = 3x-2x+2= x+2

4) = -5x+35+3x-2= -2x+33

5) = 9a+3b-11

6) = 2x-5+3x-2= 5x-7

7) = 2x-3-2x+2= -1

8) =-x-3-x-4= -2x-7

9) =-x-3-2x-4= -3x-7

10)= -5x-35-2x-6= -7x-41

11) =-(1/3)/(5x-10)= (-1/15x)-(-1/30)

Answer 2

3x+7-5x-11=

-2x-4=

-2x=4/(-2)=

x=-2

 

2(x-7+3x)=

2x-14+6x=

8x=14/8

x=14/8

x=1 6/8

x=1 3/4

3x-2(x-1)=

3x-2x+2=

x=-2

 

-5(x-7)+3x-2=

-5x+35+3x-2=

2x=-33/2

x=16 1/2

 

2a+3b+7a-11=

9a+3b-11

 

1/2(4x-10)+3x-2=

2x-5+3x-2=

5x=7/5=

x=7/5

x=1 2/5

 

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

2x-3-2x+2=

0x=-1

 

-(x+3)-(1x+4)=

-x-3-x-4=

-2x=7/(-2)

x=-7/2

x=-3 1/2

 

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

-x-3-2x-8=

-3x=11/(-3)

x=-11/3

x=-3 2/3

 

5(-x-7)-2(x+3)=

-5x-35-2x-21=

-7x=56/(-7)

x=-56/7

x=-8

 

(5x-10)/(-1/3)=

(5x-10)razy(-3/1)=

-15/1x-30/1=

-15x=30/(-15)=

x=-2

 

myśle że to o to chodziło
