[ 1/1 Equation]
Work: Find the solution of equation （7.12*2100+3.12*X）/(2100+X) = 3.12 .
Question type: Equation
Solution:Original question:
| ( | 178 25 | × | 2100 | + | 78 25 | X | ) | ÷ | ( | 2100 | + | X | ) | = | 78 25 |
| Multiply both sides of the equation by: | ( | 2100 | + | X | ) |
| ( | 178 25 | × | 2100 | + | 78 25 | X | ) | = | 78 25 | ( | 2100 | + | X | ) |
178 25 | × | 2100 | + | 78 25 | X | = | 78 25 | ( | 2100 | + | X | ) |
178 25 | × | 2100 | + | 78 25 | X | = | 78 25 | × | 2100 | + | 78 25 | X |
| 14952 | + | 78 25 | X | = | 6552 | + | 78 25 | X |
Transposition :
78 25 | X | − | 78 25 | X | = | 6552 | − | 14952 |
Combine the items on the left of the equation:
| 0 | X | = | 6552 | − | 14952 |
Combine the items on the right of the equation:
| 0 | X | = | - | 8400 |
Error: This Equation has no solution!!
