Work: Find the solution of equation 6x-15 = -4x .
Question type: Equation
Solution:Original question:
| 6 | x | − | 15 | = | - | 4 | x |
Transposition :
| 6 | x | + | 4 | x | = | 15 |
Combine the items on the left of the equation:
| 10 | x | = | 15 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 15 | ÷ | 10 |
| = | 15 | × | 1 10 |
| = | 3 | × | 1 2 |
We obtained :
| x | = | 3 2 |
Convert the result to decimal form :
| x | = | 1.5 |
