how would you solve this.....

500x - 0.81 = 900x + 0.67

1. add 0.81 to both sides
2. subtract 900x from both sides
3. simplify
4. divide both sides by what you are multiplying "x" by
5. at this point, the left side should be just x, and the right side the solution

could you show me please!!!! I dont know crap!!! SMH!!!!!

step 1:

500x - 0.81 + 0.81 = 900x + 0.67 + 0.81

step 2:

500x - 0.81 + 0.81 - 900x = 900x + 0.67 + 0.81 - 900x

step 3:

put the "x stuff" together, and the "non-x stuff" together:

500x - 900x - 0.81 + 0.81 = 900x - 900x + 0.67 + 0.81

now we can simply things:

-0.81 + 0.81 = 0, and 500x - 900x + 0 = 500x - 900x, so the left side becomes: 500x - 900x.

900x - 900x = 0, and 0 + 0.67 + 0.81 = 0.67 + 0.81, so the right side becomes: 0.67 + 0.81, so now we have:

500x - 900x = 0.67 + 0.81

by the distributive law: 500x - 900x = (500 - 900)x = -400x, and 0.67 + 0.81 = 1.48, so now we have:

-400x = 1.48

step 4: well, you don't really expect me to finish it ALL for you, do you?

This is the best solution..

500x - 0.81 = 900x + 0.67

500x - 900x = 0.81 + 0.67

-400x = 1.48

-400 -400

x = - 0.0037
