☆3 equations
[ 1/3 Equation]
Work: Find the solution of equation 104*0.03+x*0.97 = 250 .
Question type: Equation
Solution:Original question:
| 104 | × | 3 100 | + | x | × | 97 100 | = | 250 |
| Left side of the equation = | 78 25 | + | x | × | 97 100 |
78 25 | + | 97 100 | x | = | 250 |
Transposition :
97 100 | x | = | 250 | − | 78 25 |
Combine the items on the right of the equation:
97 100 | x | = | 6172 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6172 25 | ÷ | 97 100 |
| = | 6172 25 | × | 100 97 |
| = | 6172 | × | 4 97 |
We obtained :
| x | = | 24688 97 |
Convert the result to decimal form :
| x | = | 254.515464 |
[ 2/3 Equation]
Work: Find the solution of equation 138*0.03+x*0.97 = 226 .
Question type: Equation
Solution:Original question:
| 138 | × | 3 100 | + | x | × | 97 100 | = | 226 |
| Left side of the equation = | 207 50 | + | x | × | 97 100 |
207 50 | + | 97 100 | x | = | 226 |
Transposition :
97 100 | x | = | 226 | − | 207 50 |
Combine the items on the right of the equation:
97 100 | x | = | 11093 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 11093 50 | ÷ | 97 100 |
| = | 11093 50 | × | 100 97 |
| = | 11093 | × | 2 97 |
We obtained :
| x | = | 22186 97 |
Convert the result to decimal form :
| x | = | 228.721649 |
[ 3/3 Equation]
Work: Find the solution of equation 206*0.03+x*0.97 = 130 .
Question type: Equation
Solution:Original question:
| 206 | × | 3 100 | + | x | × | 97 100 | = | 130 |
| Left side of the equation = | 309 50 | + | x | × | 97 100 |
309 50 | + | 97 100 | x | = | 130 |
Transposition :
97 100 | x | = | 130 | − | 309 50 |
Combine the items on the right of the equation:
97 100 | x | = | 6191 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 6191 50 | ÷ | 97 100 |
| = | 6191 50 | × | 100 97 |
| = | 6191 | × | 2 97 |
We obtained :
| x | = | 12382 97 |
Convert the result to decimal form :
| x | = | 127.649485 |
