Example

-2/3x-3=17

+3 +3

0 20


First you want to add the three to the other side because the opposite of negative is positive.

-3/2 -2/3x=20 -3/2

Then you want to flip the -2/3 then multiply both sides by that.

The -2/3 cancels out then you want to multiply the other side.

x=20/1 - 3/2 <--Multiply straight across

x= - 60/2 <--Simplify

x= - 30
