Work: Find the solution of equation 24.75 = (2.88-2.38+1.9-x)/4×0.01 .
Question type: Equation
Solution:Original question:
99 4 | = | ( | 72 25 | − | 119 50 | + | 19 10 | − | x | ) | ÷ | 4 | × | 1 100 |
| Right side of the equation = | ( | 72 25 | − | 119 50 | + | 19 10 | − | x | ) | × | 1 400 |
99 4 | = | ( | 72 25 | − | 119 50 | + | 19 10 | − | x | ) | × | 1 400 |
| Right side of the equation = | 72 25 | × | 1 400 | − | 119 50 | × | 1 400 | + | 19 10 | × | 1 400 | − | x | × | 1 400 |
| = | 9 1250 | − | 119 20000 | + | 19 4000 | − | x | × | 1 400 |
| = | 3 500 | − | 1 400 | x |
99 4 | = | 3 500 | − | 1 400 | x |
Transposition :
1 400 | x | = | 3 500 | − | 99 4 |
Combine the items on the right of the equation:
1 400 | x | = | - | 3093 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 3093 125 | ÷ | 1 400 |
| = | - | 3093 125 | × | 400 |
| = | - | 3093 5 | × | 16 |
We obtained :
| x | = | - | 49488 5 |
Convert the result to decimal form :
| x | = | - 9897.6 |
