Work: Find the solution of equation 1.5+0.07*(12+0.035*(50+0.013*200)) = x .
Question type: Equation
Solution:Original question:
3 2 | + | 7 100 | ( | 12 | + | 7 200 | ( | 50 | + | 13 1000 | × | 200 | ) | ) | = | x |
| Left side of the equation = | 3 2 | + | 7 100 | × | 12 | + | 7 100 | × | 7 200 | ( | 50 | + | 13 1000 | × | 200 | ) |
| = | 3 2 | + | 21 25 | + | 49 20000 | ( | 50 | + | 13 1000 | × | 200 | ) |
| = | 117 50 | + | 49 20000 | ( | 50 | + | 13 1000 | × | 200 | ) |
| = | 117 50 | + | 49 20000 | × | 50 | + | 49 20000 | × | 13 1000 | × | 200 |
| = | 117 50 | + | 49 400 | + | 637 100000 |
| = | 246887 100000 |
246887 100000 | = | x |
Transposition :
| - | x | = | - | 246887 100000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
246887 100000 | = | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
| x | = | 246887 100000 |
This is the solution of the equation.
