[ 1/1 Equation]
Work: Find the solution of equation 2194.2 = （87-x）32.9+19.8x .
Question type: Equation
Solution:Original question:
10971 5 | = | ( | 87 | − | x | ) | × | 329 10 | + | 99 5 | x |
| Right side of the equation = | 87 | × | 329 10 | − | x | × | 329 10 | + | 99 5 | x |
| = | 28623 10 | − | x | × | 329 10 | + | 99 5 | x |
| = | 28623 10 | − | 131 10 | x |
10971 5 | = | 28623 10 | − | 131 10 | x |
Transposition :
131 10 | x | = | 28623 10 | − | 10971 5 |
Combine the items on the right of the equation:
131 10 | x | = | 6681 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6681 10 | ÷ | 131 10 |
| = | 6681 10 | × | 10 131 |
| = | 6681 | × | 1 131 |
We obtained :
| x | = | 6681 131 |
By reducing fraction, we can get:
| x | = | 51 |
