[ 1/1 Equation]
Work: Find the solution of equation （41.789+x）×1.75 = 71.878+41.789-x .
Question type: Equation
Solution:Original question:
| ( | 41789 1000 | + | x | ) | × | 7 4 | = | 35939 500 | + | 41789 1000 | − | x |
| Left side of the equation = | 41789 1000 | × | 7 4 | + | x | × | 7 4 |
| = | 292523 4000 | + | x | × | 7 4 |
292523 4000 | + | 7 4 | x | = | 35939 500 | + | 41789 1000 | − | x |
| Right side of the equation = | 113667 1000 | − | x |
292523 4000 | + | 7 4 | x | = | 113667 1000 | − | x |
Transposition :
7 4 | x | + | x | = | 113667 1000 | − | 292523 4000 |
Combine the items on the left of the equation:
11 4 | x | = | 113667 1000 | − | 292523 4000 |
Combine the items on the right of the equation:
11 4 | x | = | 32429 800 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 32429 800 | ÷ | 11 4 |
| = | 32429 800 | × | 4 11 |
| = | 32429 200 | × | 1 11 |
We obtained :
| x | = | 32429 2200 |
Convert the result to decimal form :
| x | = | 14.740455 |
