[ 1/1 Equation]
Work: Find the solution of equation 0.5/378.15+0.5/219.15 = 1/x .
Question type: Equation
Solution:Original question:
1 2 | ÷ | 7563 20 | + | 1 2 | ÷ | 4383 20 | = | 1 | ÷ | x |
| Multiply both sides of the equation by: | x |
1 2 | ÷ | 7563 20 | × | x | + | 1 2 | ÷ | 4383 20 | × | x | = | 1 |
Calculate the items on the left of the equation:
10 7563 | x | + | 10 4383 | x | = | 1 |
Combine the items on the left of the equation:
39820 11049543 | x | = | 1 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1 | ÷ | 39820 11049543 |
| = | 1 | × | 11049543 39820 |
We obtained :
| x | = | 11049543 39820 |
Convert the result to decimal form :
| x | = | 277.487268 |
