Work: Find the solution of equation 7.99×110+50.8x = 160.8×7.96 .
Question type: Equation
Solution:Original question:
799 100 | × | 110 | + | 254 5 | x | = | 804 5 | × | 199 25 |
| Left side of the equation = | 8789 10 | + | 254 5 | x |
8789 10 | + | 254 5 | x | = | 804 5 | × | 199 25 |
| Right side of the equation = | 159996 125 |
8789 10 | + | 254 5 | x | = | 159996 125 |
Transposition :
254 5 | x | = | 159996 125 | − | 8789 10 |
Combine the items on the right of the equation:
254 5 | x | = | 100267 250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 100267 250 | ÷ | 254 5 |
| = | 100267 250 | × | 5 254 |
| = | 100267 50 | × | 1 254 |
We obtained :
| x | = | 100267 12700 |
Convert the result to decimal form :
| x | = | 7.895039 |
