[ 1/1 Equation]
Work: Find the solution of equation 450x-310.02-240x-(450x*0.13-15*-30.4)*0.12 = 0 .
Question type: Equation
Solution:Original question:
| 450 | x | − | 15501 50 | − | 240 | x | − | ( | 450 | x | × | 13 100 | − | 15 | − | 152 5 | ) | × | 3 25 | = | 0 |
| Left side of the equation = | 210 | x | − | 15501 50 | − | ( | 450 | x | × | 13 100 | − | 15 | − | 152 5 | ) | × | 3 25 |
| 210 | x | − | 15501 50 | − | ( | 450 | x | × | 13 100 | − | 15 | − | 152 5 | ) | × | 3 25 | = | 0 |
| Left side of the equation = | 210 | x | − | 15501 50 | − | 450 | x | × | 13 100 | × | 3 25 | + | 15 | × | 3 25 | + | 152 5 | × | 3 25 |
| = | 210 | x | − | 15501 50 | − | 351 50 | x | + | 9 5 | + | 456 125 |
| = | 10149 50 | x | − | 76143 250 |
10149 50 | x | − | 76143 250 | = | 0 |
Transposition :
10149 50 | x | = | 0 | + | 76143 250 |
Combine the items on the right of the equation:
10149 50 | x | = | 76143 250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 76143 250 | ÷ | 10149 50 |
| = | 76143 250 | × | 50 10149 |
| = | 1493 5 | × | 1 199 |
We obtained :
| x | = | 1493 995 |
Convert the result to decimal form :
| x | = | 1.500503 |
