Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3-(x/(33/10))=0

Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 33 as the denominator :
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
Now, on the left hand side, the 33 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
99-10x = 0 Keepassxc 2 5 1000.
Solving a Single Variable Equation :
4.2 Solve : -10x+99 = 0
Subtract 99 from both sides of the equation :
-10x = -99
Multiply both sides of the equation by (-1) : 10x = 99
Divide both sides of the equation by 10:
x = 99/10 = 9.900
