Answer:
Step 1: simplify 3/4
(3/4 • a) - 16 = 0
Rewrite the whole as a fraction using 4 as the denominator
16= 16/1 = 16 * 4/4
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible
3a - ( 16 *4 ) / 4 = 3a - 64 / 4
Step 2: 3a - 64 / 4 = 0
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 multiply's both sides of the equation by the denominator.
3a - 64 / 4 * 4 = 0 * 4
Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
3a - 64 = 0
Solving Single Variable Equation
Solve : 3a-64 = 0
Add 64 to both sides of the equation :
3a = 64
Divide both sides of the equation by 3:
a = 64/3 = 21.333
