[ 1/1 Equation]
Work: Find the solution of equation 5/131-0/1300-70/1650+X/126+7.8/87 = 0.00243(82.8+X) .
Question type: Equation
Solution:Original question:
| 5 | ÷ | 131 | − | 0 | ÷ | 1300 | − | 70 | ÷ | 1650 | + | X | ÷ | 126 | + | 39 5 | ÷ | 87 | = | 243 100000 | ( | 414 5 | + | X | ) |
| Left side of the equation = | 5 131 | − | 0 | − | 7 165 | + | X | × | 1 126 | + | 13 145 |
| = | 53531 626835 | + | 1 126 | X |
53531 626835 | + | 1 126 | X | = | 243 100000 | ( | 414 5 | + | X | ) |
| Right side of the equation = | 243 100000 | × | 414 5 | + | 243 100000 | X |
| = | 50301 250000 | + | 243 100000 | X |
53531 626835 | + | 1 126 | X | = | 50301 250000 | + | 243 100000 | X |
Transposition :
1 126 | X | − | 243 100000 | X | = | 50301 250000 | − | 53531 626835 |
Combine the items on the left of the equation:
34691 6300000 | X | = | 50301 250000 | − | 53531 626835 |
X≈21.030594 , keep 6 decimal places
