Step by Step Solution
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "3.2" was replaced by "(32/10)".
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
(32/10)/100*x-(8)=0
Step by step solution :
Step 1 :
16
Simplify ——
5
Equation at the end of step 1 :
16
(—— ÷ 100 • x) - 8 = 0
5
Step 2 :
16
Divide —— by 100
5
Equation at the end of step 2 :
4
(——— • x) - 8 = 0
125
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 125 as the denominator :
8 8 • 125
8 = — = ———————
1 125
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:
4x - (8 • 125) 4x - 1000
—————————————— = —————————
125 125
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
4x - 1000 = 4 • (x - 250)
Equation at the end of step 4 :
4 • (x - 250)
————————————— = 0
125
Step 5 :
When a fraction equals zero :
5.1 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:
4•(x-250)
————————— • 125 = 0 • 125
125
Now, on the left hand side, the 125 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
4 • (x-250) = 0
Equations which are never true :
5.2 Solve : 4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
5.3 Solve : x-250 = 0
Add 250 to both sides of the equation :
x = 250
One solution was found :
x = 250How did we do?
