[ 1/1 Equation]
Work: Find the solution of equation 88 = 1.9643*22.4*(5-2y) .
Question type: Equation
Solution:Original question:
| 88 | = | 19643 10000 | × | 112 5 | ( | 5 | − | 2 | y | ) |
| Right side of the equation = | 137501 3125 | ( | 5 | − | 2 | y | ) |
| 88 | = | 137501 3125 | ( | 5 | − | 2 | y | ) |
| Right side of the equation = | 137501 3125 | × | 5 | − | 137501 3125 | × | 2 | y |
| = | 137501 625 | − | 275002 3125 | y |
| 88 | = | 137501 625 | − | 275002 3125 | y |
Transposition :
275002 3125 | y | = | 137501 625 | − | 88 |
Combine the items on the right of the equation:
275002 3125 | y | = | 82501 625 |
The coefficient of the unknown number is reduced to 1 :
| y | = | 82501 625 | ÷ | 275002 3125 |
| = | 82501 625 | × | 3125 275002 |
| = | 82501 | × | 5 275002 |
We obtained :
| y | = | 412505 275002 |
Convert the result to decimal form :
| y | = | 1.500007 |
