4х-1=2(х+0,3) 5/6х+1 2/3=2х-3 3= 5 _____________ 2х-1= 3х-2

Question

4х-1=2(х+0,3)

5/6х+1 2/3=2х-3

3= 5

_____________

2х-1= 3х-2

Answer 1

4х-1=2(х+0,3)

4х-1=2х+0,6

4х-2х=0,6+1

2х=1,6

х=0,8

 

5/6x+1 2/3=2x-3

5/6х-2х=-3-1 2/3

-7/6х=-4 2/3

х=4

 

  3          5 

----- =   -----

2x-1    3x-2

 

(2х-1)*5=(3х-2)*3

10х-5=9х-6

10х-9х=-6+5

х=-1

Answer 2

4x-1=2(x+0,3)
4x-1-2x-0.6=0
2x-1.6=0

x=1.6/2

x=0.8

 

5//6x+1 2//3=2x-3

-7//6x+14//3=0

x=(-14//3)/(-7//6)
x=4 

 

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

10х-5=9х-6

x-5+6=0

х=-1
