SOLUTION: Can anyone tell me if I did this right. x/10=9/30 Solve for x Factors 9 and 30 have greatest common factor of 3. Reducing fraction. It becomes x/10=3/10 Move these

Question 117201: Can anyone tell me if I did this right.
x/10=9/30
Solve for x
Factors 9 and 30 have greatest common factor of 3. Reducing fraction.
It becomes x/10=3/10
Move these terms to the left - 3/10
It now becomes x/10-3/10=0
Solved linear equation x/10-3/10 equivalent to 0.1�x-0.3=0
It becomes 0=0
Solution x=3
If not can you show me where I went wrong.

Start with the given equation

Multiply both sides by 10

Multiply

Simplify

So our answer is

So you are correct, but I'm not sure where you got the step "0=0". As always, you can check this by plugging the solution back into the original equation

--------------------------------------
Check:

Start with the given equation

Plug in x=3

Reduce the right side. Since the two sides of the equation are equal, this verifies our answer.

Solved linear equation x/10-3/10 equivalent to 0.1�x-0.3=0
0.1x = 0.3
x = 0.3/0.1
x = 3
