Solution - Linear equations with one unknown
x=20
Step by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
200^8*x-(4000)=0
Step by step solution :
Step 1 :
1.1 200 = 23•52
(200)8 = (23•52)8 = 224 • 516
Equation at the end of step 1 :
((224•516) • x) - 4000 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
224 • 516x - 4000 = 200 • (x - 20)
Equation at the end of step 3 :
200 • (x - 20) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 200 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x-20 = 0
Add 20 to both sides of the equation :
x = 20
One solution was found :
x = 20How did we do?
