[ 1/1 Equation]
Work: Find the solution of equation 0.3x/12+0.7x/10 = 8800 .
Question type: Equation
Solution:Original question:
3 10 | x | ÷ | 12 | + | 7 10 | x | ÷ | 10 | = | 8800 |
| Left side of the equation = | 1 40 | x | + | 7 100 | x |
| = | 19 200 | x |
19 200 | x | = | 8800 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 8800 | ÷ | 19 200 |
| = | 8800 | × | 200 19 |
We obtained :
| x | = | 1760000 19 |
Convert the result to decimal form :
| x | = | 92631.578947 |
