Work: Find the solution of equation 55×7.99+105.6×7.94 = 160.6x .
Question type: Equation
Solution:Original question:
| 55 | × | 799 100 | + | 528 5 | × | 397 50 | = | 803 5 | x |
| Left side of the equation = | 8789 20 | + | 104808 125 |
| = | 638957 500 |
638957 500 | = | 803 5 | x |
Transposition :
| - | 803 5 | x | = | - | 638957 500 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
638957 500 | = | 803 5 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
803 5 | x | = | 638957 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 638957 500 | ÷ | 803 5 |
| = | 638957 500 | × | 5 803 |
| = | 58087 100 | × | 1 73 |
We obtained :
| x | = | 58087 7300 |
Convert the result to decimal form :
| x | = | 7.957123 |
