[ 1/1 Equation]
Work: Find the solution of equation （5*220+92*x）/8.14 = （92*（30-x）+80*（43.26+x））/73.26 .
Question type: Equation
Solution:Original question:
| ( | 5 | × | 220 | + | 92 | x | ) | ÷ | 407 50 | = | ( | 92 | ( | 30 | − | x | ) | + | 80 | ( | 2163 50 | + | x | ) | ) | ÷ | 3663 50 |
| Left side of the equation = | 5 | × | 220 | × | 50 407 | + | 92 | x | × | 50 407 |
| = | 5000 37 | + | 4600 407 | x |
5000 37 | + | 4600 407 | x | = | ( | 92 | ( | 30 | − | x | ) | + | 80 | ( | 2163 50 | + | x | ) | ) | ÷ | 3663 50 |
| Right side of the equation = | 92 | ( | 30 | − | x | ) | × | 50 3663 | + | 80 | ( | 2163 50 | + | x | ) | × | 50 3663 |
| = | 4600 3663 | ( | 30 | − | x | ) | + | 4000 3663 | ( | 2163 50 | + | x | ) |
| = | 4600 3663 | × | 30 | − | 4600 3663 | x | + | 4000 3663 | ( | 2163 50 | + | x | ) |
| = | 46000 1221 | − | 4600 3663 | x | + | 4000 3663 | ( | 2163 50 | + | x | ) |
| = | 46000 1221 | − | 4600 3663 | x | + | 4000 3663 | × | 2163 50 | + | 4000 3663 | x |
| = | 46000 1221 | − | 4600 3663 | x | + | 57680 1221 | + | 4000 3663 | x |
| = | 34560 407 | − | 200 1221 | x |
5000 37 | + | 4600 407 | x | = | 34560 407 | − | 200 1221 | x |
Transposition :
4600 407 | x | + | 200 1221 | x | = | 34560 407 | − | 5000 37 |
Combine the items on the left of the equation:
14000 1221 | x | = | 34560 407 | − | 5000 37 |
Combine the items on the right of the equation:
14000 1221 | x | = | - | 20440 407 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 20440 407 | ÷ | 14000 1221 |
| = | - | 20440 407 | × | 1221 14000 |
| = | - | 73 | × | 3 50 |
We obtained :
| x | = | - | 219 50 |
Convert the result to decimal form :
| x | = | - 4.38 |
