ax=b

3x = 0.6 <-- you need to divide both sides by 3

3x/3 = 0.6/3

x=0.2

LS RS check ;

3x=0.6

3(0.2)

0.6

x/a = b <-- you can multiply (a)(b)

x/5 = 0.3

5(x/5) = 5(0.3)

x = 1.5

LS RS check ;

x/5 = 0.3

x = 1.5/0.3

a/x = b

3.3/x = 1.1

x(3/3) = 1.1x

3.3/1.1 = 1.1x/1.1

3=x <--You can do it like this or ...

x=3 <-- this is the more proper way

LS RS ;

3.3/x = 1.1

3.3/3

1.1

2x = 3/4

Divide 2 by itself = 3/4 . 2/1

x = 3/4 x 1/2 . 2/1 x 1/2 makes 0.

3/4 x 1/2 = 3/8

LS RS check ;

2x = 3/4

2/1(3/8) =

6/8

3/4.

another way to the previous question is ...

2x/1 = 3/4

(2x)(4) = 3

8x/8 = 3/8

x = 3/8

-2 1/2x = -3 1/2 <-- make into a proper fraction

-5/2x = -7/2

x = -7/-5

another way of doing it ;

-5/2x = -7/2

-5/2 x -2/5

x = 7/5

and another way ...

-5/2x = -7/2

-5x(2) = 2(-7)

-10x/-10 = -14/-10

x = 14/10 or 7/5
