Work: Find the solution of equation 3.5944*143+4.0*2+4*2+3.4*2 = (143+2+2+2)*x .
Question type: Equation
Solution:Original question:
4493 1250 | × | 143 | + | 4 | × | 2 | + | 4 | × | 2 | + | 17 5 | × | 2 | = | ( | 143 | + | 2 | + | 2 | + | 2 | ) | x |
| Left side of the equation = | 642499 1250 | + | 8 | + | 8 | + | 34 5 |
| = | 670999 1250 |
670999 1250 | = | ( | 143 | + | 2 | + | 2 | + | 2 | ) | x |
| Right side of the equation = | 143 | x | + | 2 | x | + | 2 | x | + | 2 | x |
| = | 149 | x |
670999 1250 | = | 149 | x |
Transposition :
| - | 149 | x | = | - | 670999 1250 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
670999 1250 | = | 149 | 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 :
| 149 | x | = | 670999 1250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 670999 1250 | ÷ | 149 |
| = | 670999 1250 | × | 1 149 |
We obtained :
| x | = | 670999 186250 |
Convert the result to decimal form :
| x | = | 3.602679 |
