Work: Find the solution of equation 35 = 165.7×(0.15+x)×(1+2÷0.15x) .
Question type: Equation
Solution:Original question:
| 35 | = | 1657 10 | ( | 3 20 | + | x | ) | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) |
| Right side of the equation = | 1657 10 | × | 3 20 | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) | + | 1657 10 | x | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) |
| = | 4971 200 | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) | + | 1657 10 | x | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) |
| = | 4971 200 | × | 1 | + | 4971 200 | × | 2 | ÷ | 3 20 | × | x | + | 1657 10 | x | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) |
| = | 4971 200 | + | 1657 5 | x | + | 1657 10 | x | ( | 1 | + | 2 | ÷ | 3 20 | × | x | ) |
| = | 4971 200 | + | 1657 5 | x | + | 1657 10 | x | × | 1 | + | 1657 10 | x | × | 2 | ÷ | 3 20 | × | x |
| = | 4971 200 | + | 1657 5 | x | + | 1657 10 | x | + | 6628 3 | x | x |
| = | 4971 200 | + | 4971 10 | x | + | 6628 3 | x | x |
| 35 | = | 4971 200 | + | 4971 10 | x | + | 6628 3 | x | x |
