Work: Find the solution of equation 6x+3x = 600 .
Question type: Equation
Solution:Original question:
| 6 | x | + | 3 | x | = | 600 |
| Left side of the equation = | 9 | x |
| 9 | x | = | 600 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 600 | ÷ | 9 |
| = | 600 | × | 1 9 |
| = | 200 | × | 1 3 |
We obtained :
| x | = | 200 3 |
Convert the result to decimal form :
| x | = | 66.666667 |
