Work: Find the solution of equation （39.402+x）×2.2 = 39.402+72.604-x .
Question type: Equation
Solution:Original question:
| ( | 19701 500 | + | x | ) | × | 11 5 | = | 19701 500 | + | 18151 250 | − | x |
| Left side of the equation = | 19701 500 | × | 11 5 | + | x | × | 11 5 |
| = | 216711 2500 | + | x | × | 11 5 |
216711 2500 | + | 11 5 | x | = | 19701 500 | + | 18151 250 | − | x |
| Right side of the equation = | 56003 500 | − | x |
216711 2500 | + | 11 5 | x | = | 56003 500 | − | x |
Transposition :
11 5 | x | + | x | = | 56003 500 | − | 216711 2500 |
Combine the items on the left of the equation:
16 5 | x | = | 56003 500 | − | 216711 2500 |
Combine the items on the right of the equation:
16 5 | x | = | 15826 625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 15826 625 | ÷ | 16 5 |
| = | 15826 625 | × | 5 16 |
| = | 7913 125 | × | 1 8 |
We obtained :
| x | = | 7913 1000 |
Convert the result to decimal form :
| x | = | 7.913 |
