[ 1/1 Equation]
Work: Find the solution of equation (x+4.28)*1.38 = 82 .
Question type: Equation
Solution:Original question:
| ( | x | + | 107 25 | ) | × | 69 50 | = | 82 |
| Left side of the equation = | x | × | 69 50 | + | 107 25 | × | 69 50 |
| = | x | × | 69 50 | + | 7383 1250 |
69 50 | x | + | 7383 1250 | = | 82 |
Transposition :
69 50 | x | = | 82 | − | 7383 1250 |
Combine the items on the right of the equation:
69 50 | x | = | 95117 1250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 95117 1250 | ÷ | 69 50 |
| = | 95117 1250 | × | 50 69 |
| = | 95117 25 | × | 1 69 |
We obtained :
| x | = | 95117 1725 |
Convert the result to decimal form :
| x | = | 55.14029 |
