Work: Find the solution of equation （25.626+x）×2.35 = 51.253+71.679-x .
Question type: Equation
Solution:Original question:
| ( | 12813 500 | + | x | ) | × | 47 20 | = | 51253 1000 | + | 71679 1000 | − | x |
| Left side of the equation = | 12813 500 | × | 47 20 | + | x | × | 47 20 |
| = | 602211 10000 | + | x | × | 47 20 |
602211 10000 | + | 47 20 | x | = | 51253 1000 | + | 71679 1000 | − | x |
| Right side of the equation = | 30733 250 | − | x |
602211 10000 | + | 47 20 | x | = | 30733 250 | − | x |
Transposition :
47 20 | x | + | x | = | 30733 250 | − | 602211 10000 |
Combine the items on the left of the equation:
67 20 | x | = | 30733 250 | − | 602211 10000 |
Combine the items on the right of the equation:
67 20 | x | = | 627109 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 627109 10000 | ÷ | 67 20 |
| = | 627109 10000 | × | 20 67 |
| = | 627109 500 | × | 1 67 |
We obtained :
| x | = | 627109 33500 |
Convert the result to decimal form :
| x | = | 18.719672 |
