Question

Obliczcie i rozwiązcie jak na gimnazjum (prosto)

1. x-5/10+2x+5/2=2-x/5

2.x+4/5+2x+9/10=-2-x/2

3.x+4/2+6-x\3=2x-5/6

4. 28-11/4+x+1/12=x-1/6

1.

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

2.

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

3.

2x-3/6-8-x/9=x+3/18

4, 2x-1/4-x-1\2=5x-9/4

Answer 1

x+5/10+2x+5/2=2-x/5/ *10

x+5+10x+25=4-2x

x+10x+2x=4-25-5

13x=-26/13

x=-2

_____________________  

X + 4/5 + 2x + 9/10 = -2 - x/2 = 4 x/5 = 11/10 = 1x/2 + 16/100 =1600 

 

 

_______________________

x-4 / 2 + 6-x / 3 = 2x-5 /6 /*12
6x-24+24-4x=4x-10
-2x=-10
x=5

 1.

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

a). x-1/3 - x-2/2=2x-5/6    /razy szesc

2x-2 - 3x-6 = 2x-5       / przerzucasz wiadome na prawo reszta na lewo

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

-3x=3     /podzielic przez -3

x=-1

 

3.

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

 

2x-3/6 - 8-x/9 = x+3/18        |*18

3(2x-3)-2(8-x)=x+3

6x-9-16+2x=x+3

8x-25=x+3

7x=-22

x=-22/7

x=-3¹/₇

 

 

4) 2x-1/4 - x-1/2 = 5x-9/4       |*4

2x-1-2(x-1)=5x-9

2x-1-2x-2=5x-9

-3=5x-9

-5x=-6

x=6/5

x=1⅕
