Work: Find the solution of equation （39.402+x）×1.75 = 39.402+71.604-x .
Question type: Equation
Solution:Original question:
| ( | 19701 500 | + | x | ) | × | 7 4 | = | 19701 500 | + | 17901 250 | − | x |
| Left side of the equation = | 19701 500 | × | 7 4 | + | x | × | 7 4 |
| = | 137907 2000 | + | x | × | 7 4 |
137907 2000 | + | 7 4 | x | = | 19701 500 | + | 17901 250 | − | x |
| Right side of the equation = | 55503 500 | − | x |
137907 2000 | + | 7 4 | x | = | 55503 500 | − | x |
Transposition :
7 4 | x | + | x | = | 55503 500 | − | 137907 2000 |
Combine the items on the left of the equation:
11 4 | x | = | 55503 500 | − | 137907 2000 |
Combine the items on the right of the equation:
11 4 | x | = | 16821 400 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 16821 400 | ÷ | 11 4 |
| = | 16821 400 | × | 4 11 |
| = | 16821 100 | × | 1 11 |
We obtained :
| x | = | 16821 1100 |
Convert the result to decimal form :
| x | = | 15.291818 |
