[ 1/1 Equation]
Work: Find the solution of equation (11.2-x)+(1.07*1.09)x = 12.92 .
Question type: Equation
Solution:Original question:
| ( | 56 5 | − | x | ) | + | ( | 107 100 | × | 109 100 | ) | x | = | 323 25 |
| Left side of the equation = | 56 5 | − | x | + | ( | 107 100 | × | 109 100 | ) | x |
| = | 56 5 | − | x | + | 107 100 | × | 109 100 | x |
| = | 56 5 | − | x | + | 11663 10000 | x |
| = | 56 5 | + | 1663 10000 | x |
56 5 | + | 1663 10000 | x | = | 323 25 |
Transposition :
1663 10000 | x | = | 323 25 | − | 56 5 |
Combine the items on the right of the equation:
1663 10000 | x | = | 43 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 43 25 | ÷ | 1663 10000 |
| = | 43 25 | × | 10000 1663 |
| = | 43 | × | 400 1663 |
We obtained :
| x | = | 17200 1663 |
Convert the result to decimal form :
| x | = | 10.342754 |
