Answer: x=30
Step-by-step explanation: Adding a whole to a fraction
Rewrite the whole as a fraction using 3 as the denominator :
9=9/1=9.3/3
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
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, multiply both sides of the equation by the denominator.
Here's how:
x-30
/6• 6 = 0 • 6
Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-30 = 0
x-30 = 0
Add 30 to both sides of the equation :
x = 30
