[ 1/1 Equation]
Work: Find the solution of equation X*0.82*42+X*0.18*15 = 23000*0.5 .
Question type: Equation
Solution:Original question:
| X | × | 41 50 | × | 42 | + | X | × | 9 50 | × | 15 | = | 23000 | × | 1 2 |
| Left side of the equation = | X | × | 861 25 | + | X | × | 27 10 |
| = | 1857 50 | X |
1857 50 | X | = | 23000 | × | 1 2 |
| Right side of the equation = | 11500 |
1857 50 | X | = | 11500 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 11500 | ÷ | 1857 50 |
| = | 11500 | × | 50 1857 |
We obtained :
| X | = | 575000 1857 |
Convert the result to decimal form :
| X | = | 309.639203 |
