[ 3/3 Equation]
Work: Find the solution of equation q1+q2 = 20 .
Question type: Equation
Solution:Original question:
| q | × | 1 | + | q | × | 2 | = | 20 |
| Left side of the equation = | 3 | q |
| 3 | q | = | 20 |
The coefficient of the unknown number is reduced to 1 :
| q | = | 20 | ÷ | 3 |
| = | 20 | × | 1 3 |
We obtained :
| q | = | 20 3 |
Convert the result to decimal form :
| q | = | 6.666667 |
