Work: Find the solution of equation 73×7.98+87.6x = 160.6×7.93 .
Question type: Equation
Solution:Original question:
| 73 | × | 399 50 | + | 438 5 | x | = | 803 5 | × | 793 100 |
| Left side of the equation = | 29127 50 | + | 438 5 | x |
29127 50 | + | 438 5 | x | = | 803 5 | × | 793 100 |
| Right side of the equation = | 636779 500 |
29127 50 | + | 438 5 | x | = | 636779 500 |
Transposition :
438 5 | x | = | 636779 500 | − | 29127 50 |
Combine the items on the right of the equation:
438 5 | x | = | 345509 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 345509 500 | ÷ | 438 5 |
| = | 345509 500 | × | 5 438 |
| = | 345509 100 | × | 1 438 |
We obtained :
| x | = | 345509 43800 |
By reducing fraction, we can get:
| x | = | 4733 600 |
Convert the result to decimal form :
| x | = | 7.888333 |
