Answer 1

4/9x = 1/3 |:4/9
x = 1/3*9/4
x = 3/4
x = 0,75

1/3x+1 = 5
1/3x = 5-1
1/3x = 4 |:1/3
x = 4*3
x = 12

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

x = -2x
x+2x = 0
3x = 0 |:3
x = 0

4-x = 1,3
4-1,3 = x
x = 2,7

-x-3 = x-4
-x-x = -4+3
-2x = -1 |:(-2)
x = 0,5

8,3-2x = x-4
-2x-x = -4-8,3
-3x = -12,3 |:(-3)
x = 4,1

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

1/2-x = -1/2x
0,5-x = -0,5x
-x+0,5x = -0,5
-0,5x = -0,5 |:(0,5)
x = 1

1/2x+1/5x-1/10x = 2
0,5x+0,2x-0,1x = 2
0,7x-0,1x = 2
0,6x = 2 |:0,6
x = 3i1/3

Answer 2

4/9x = 1/3 /x9
4x=3 /:4
x= 3/4

1/3x+1=5 /x3
x+3=15
x=12

3x+5= 2x
x=-5

4-x= 1,3
2,7=x

8,3-2x = x-4
-x= -12,3 /x(-1)
x=12,3

1/2x= 1/3x - 1 /x6
3x=2x -1
x=-1


1/2-x+ -1/2x =1/2-2i1/2x


1/2x+1/5x-1/10x= 2 /x10
5x+2x-x=2
6x=2 /:6
x= 2/6

Answer 3

4/9x=1/3
x= 3/4

1/3x+1=5
x=4/3

3x+5=2x
x= -5

4-x=1,3
x = 2,7

-x-3+x-4 =7

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

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

1/2-x+ -1/2x = 1/2-1 i 1/2x

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