Work: Find the solution of equation （26.493+x）×0.85 = 26.493+72.278-x .
Question type: Equation
Solution:Original question:
| ( | 26493 1000 | + | x | ) | × | 17 20 | = | 26493 1000 | + | 36139 500 | − | x |
| Left side of the equation = | 26493 1000 | × | 17 20 | + | x | × | 17 20 |
| = | 450381 20000 | + | x | × | 17 20 |
450381 20000 | + | 17 20 | x | = | 26493 1000 | + | 36139 500 | − | x |
| Right side of the equation = | 98771 1000 | − | x |
450381 20000 | + | 17 20 | x | = | 98771 1000 | − | x |
Transposition :
17 20 | x | + | x | = | 98771 1000 | − | 450381 20000 |
Combine the items on the left of the equation:
37 20 | x | = | 98771 1000 | − | 450381 20000 |
Combine the items on the right of the equation:
37 20 | x | = | 1525039 20000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1525039 20000 | ÷ | 37 20 |
| = | 1525039 20000 | × | 20 37 |
| = | 1525039 1000 | × | 1 37 |
We obtained :
| x | = | 1525039 37000 |
Convert the result to decimal form :
| x | = | 41.21727 |
