Work: Find the solution of equation 42x+20x = 24500 .
Question type: Equation
Solution:Original question:
| 42 | x | + | 20 | x | = | 24500 |
| Left side of the equation = | 62 | x |
| 62 | x | = | 24500 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 24500 | ÷ | 62 |
| = | 24500 | × | 1 62 |
| = | 12250 | × | 1 31 |
We obtained :
| x | = | 12250 31 |
Convert the result to decimal form :
| x | = | 395.16129 |
