1\2x = 1\3x-1 1

\2(x-1) =4

3(2x +3) = x-1

Answer 1

1.                                                                                  2.

1/2x=1/3x-11     *6                                                               

3x=2x-11                                                                         

3x-2x=-11                                                                        

x=-11                                                                                  

Answer 2

1/2x=1/3x-1

3/6x-2/6x = -1

1/6x = -1    /*6

x = -6

 

spr.

L = 1/2*(-6) = -3

P = 1/3*(-6)-1 = -2-1 = -3

L=P

 

1/2(x-1)=4

1/2x-1/2=4

1/2x = 4+1/2 = 9/2      /*2

x = 9

 

spr.

L = 1/2(9-1) = 1/2*8 = 4

P = 4

L=P

 

3(2x+3)=x-1

6x+9=x-1

6x-x=-1-9

5x = -10    /:5

x = -2

 

spr.

L = 3(2*(-2)+3) = 3*(-1)=-3

P = -2-1 = -3

 

L = P
