Work: Find the solution of equation 55×7.99+105.6x = 160.6×7.98 .
Question type: Equation
Solution:Original question:
| 55 | × | 799 100 | + | 528 5 | x | = | 803 5 | × | 399 50 |
| Left side of the equation = | 8789 20 | + | 528 5 | x |
8789 20 | + | 528 5 | x | = | 803 5 | × | 399 50 |
| Right side of the equation = | 320397 250 |
8789 20 | + | 528 5 | x | = | 320397 250 |
Transposition :
528 5 | x | = | 320397 250 | − | 8789 20 |
Combine the items on the right of the equation:
528 5 | x | = | 421069 500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 421069 500 | ÷ | 528 5 |
| = | 421069 500 | × | 5 528 |
| = | 38279 100 | × | 1 48 |
We obtained :
| x | = | 38279 4800 |
Convert the result to decimal form :
| x | = | 7.974792 |
