[ 1/1 Equation]
Work: Find the solution of equation 22.5×0.05×x+22.5×0.25×1.3x+22.5×0.55×1.3×1.3x+0.15×22.5×1.3×1.3×1.3×x = 240×1.1 .
Question type: Equation
Solution:Original question:
45 2 | × | 1 20 | x | + | 45 2 | × | 1 4 | × | 13 10 | x | + | 45 2 | × | 11 20 | × | 13 10 | × | 13 10 | x | = | 240 | × | 11 10 |
| Left side of the equation = | 9 8 | x | + | 117 16 | x | + | 16731 800 | x | + | 59319 8000 | x |
| = | 294129 8000 | x |
294129 8000 | x | = | 240 | × | 11 10 |
| Right side of the equation = | 264 |
294129 8000 | x | = | 264 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 264 | ÷ | 294129 8000 |
| = | 264 | × | 8000 294129 |
| = | 8 | × | 8000 8913 |
We obtained :
| x | = | 64000 8913 |
Convert the result to decimal form :
| x | = | 7.180523 |
