Work: Find the solution of equation (x/30)*9 = 783 .
Question type: Equation
Solution:Original question:
| ( | x | ÷ | 30 | ) | × | 9 | = | 783 |
| Left side of the equation = | x | ÷ | 30 | × | 9 |
| = | x | × | 3 10 |
3 10 | x | = | 783 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 783 | ÷ | 3 10 |
| = | 783 | × | 10 3 |
| = | 261 | × | 10 |
We obtained :
| x | = | 2610 |
