☆3 equations
[ 1/3 Equation]
Work: Find the solution of equation x*0.88+225*0.12 = 250 .
Question type: Equation
Solution:Original question:
| x | × | 22 25 | + | 225 | × | 3 25 | = | 250 |
| Left side of the equation = | x | × | 22 25 | + | 27 |
22 25 | x | + | 27 | = | 250 |
Transposition :
22 25 | x | = | 250 | − | 27 |
Combine the items on the right of the equation:
22 25 | x | = | 223 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 223 | ÷ | 22 25 |
| = | 223 | × | 25 22 |
We obtained :
| x | = | 5575 22 |
Convert the result to decimal form :
| x | = | 253.409091 |
[ 2/3 Equation]
Work: Find the solution of equation x*0.88+230*0.12 = 252 .
Question type: Equation
Solution:Original question:
| x | × | 22 25 | + | 230 | × | 3 25 | = | 252 |
| Left side of the equation = | x | × | 22 25 | + | 138 5 |
22 25 | x | + | 138 5 | = | 252 |
Transposition :
22 25 | x | = | 252 | − | 138 5 |
Combine the items on the right of the equation:
22 25 | x | = | 1122 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 1122 5 | ÷ | 22 25 |
| = | 1122 5 | × | 25 22 |
| = | 51 | × | 5 |
We obtained :
| x | = | 255 |
[ 3/3 Equation]
Work: Find the solution of equation x*0.88+(242*0.12) = 205 .
Question type: Equation
Solution:Original question:
| x | × | 22 25 | + | ( | 242 | × | 3 25 | ) | = | 205 |
| Left side of the equation = | 22 25 | x | + | 242 | × | 3 25 |
| = | 22 25 | x | + | 726 25 |
22 25 | x | + | 726 25 | = | 205 |
Transposition :
22 25 | x | = | 205 | − | 726 25 |
Combine the items on the right of the equation:
22 25 | x | = | 4399 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4399 25 | ÷ | 22 25 |
| = | 4399 25 | × | 25 22 |
| = | 4399 | × | 1 22 |
We obtained :
| x | = | 4399 22 |
Convert the result to decimal form :
| x | = | 199.954545 |
