Work: Find the solution of equation 1.23/1.24*(1.24+2*x) = 30 .
Question type: Equation
Solution:Original question:
123 100 | ÷ | 31 25 | × | ( | 31 25 | + | 2 | x | ) | = | 30 |
| Left side of the equation = | 123 124 | ( | 31 25 | + | 2 | x | ) |
123 124 | ( | 31 25 | + | 2 | x | ) | = | 30 |
| Left side of the equation = | 123 124 | × | 31 25 | + | 123 124 | × | 2 | x |
| = | 123 100 | + | 123 62 | x |
123 100 | + | 123 62 | x | = | 30 |
Transposition :
123 62 | x | = | 30 | − | 123 100 |
Combine the items on the right of the equation:
123 62 | x | = | 2877 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2877 100 | ÷ | 123 62 |
| = | 2877 100 | × | 62 123 |
| = | 959 50 | × | 31 41 |
We obtained :
| x | = | 29729 2050 |
Convert the result to decimal form :
| x | = | 14.501951 |
