☆2 equations
[ 1/2 Equation]
Work: Find the solution of equation 5(3-x)-12(5-2x) = -17 .
Question type: Equation
Solution:Original question:
| 5 | ( | 3 | − | x | ) | − | 12 | ( | 5 | − | 2 | x | ) | = | - | 17 |
| Left side of the equation = | 5 | × | 3 | − | 5 | x | − | 12 | ( | 5 | − | 2 | x | ) |
| = | 15 | − | 5 | x | − | 12 | ( | 5 | − | 2 | x | ) |
| = | 15 | − | 5 | x | − | 12 | × | 5 | + | 12 | × | 2 | x |
| = | 15 | − | 5 | x | − | 60 | + | 24 | x |
| = | - | 45 | + | 19 | x |
| - | 45 | + | 19 | x | = | - | 17 |
Transposition :
| 19 | x | = | - | 17 | + | 45 |
Combine the items on the right of the equation:
| 19 | x | = | 28 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 28 | ÷ | 19 |
| = | 28 | × | 1 19 |
We obtained :
| x | = | 28 19 |
Convert the result to decimal form :
| x | = | 1.473684 |
[ 2/2 Equation]
Work: Find the solution of equation 114514x÷4687 = 325437537357 .
Question type: Equation
Solution:Original question:
| 114514 | x | ÷ | 4687 | = | 325437537357 |
| Left side of the equation = | 114514 4687 | x |
114514 4687 | x | = | 325437537357 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 325437537357 | ÷ | 114514 4687 |
| = | 325437537357 | × | 4687 114514 |
We obtained :
| x | = | 1525325737592259 114514 |
