Question

1-1/4x=2-3/8

x/9+1/2=5/4-x/6+1/12

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

3(x-4)-4(2x-7)=2(x+5)

dam naj . .__.

Answer 1

1-1/4x=2-3/8

1/4x=1i5/8+1

1/4x=2i5/8/*4

x=8i20/8

x=10i1/2

 

x/9+1/2=5/4-x/6+1/12/*36

4x+18=22i1/2-6x+3

4x+6x+25i1/2

10x=25i1/2/:10

x=2,55

 

 

x-1,5-x/3=2+x/4-5/6/*12

12x-18-4x=24+3x-10

8x-3x=12+18

5x=30/:5

x=6

 

3x-12-8x+28=2x+10

-5x-2x=30+12

-7x=50/:(-)

7x=(-50)/:7

x=(-7i1/7)
