Work: Find the solution of equation 641.5 = (652－70)÷x×(0.35＋0.000000234×(652＋70)÷2) .
Question type: Equation
Solution:Original question:
1283 2 | = | ( | 652 | − | 70 | ) | ÷ | x | × | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
| Multiply both sides of the equation by: | x |
1283 2 | x | = | ( | 652 | − | 70 | ) | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
1283 2 | x | = | 652 | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) | − | 70 | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
1283 2 | x | = | 652 | × | 7 20 | + | 652 | × | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | − | 70 | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
1283 2 | x | = | 1141 5 | + | 19071 250000000 | ( | 652 | + | 70 | ) | − | 70 | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
1283 2 | x | = | 1141 5 | + | 19071 250000000 | × | 652 | + | 19071 250000000 | × | 70 | − | 70 | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
1283 2 | x | = | 1141 5 | + | 3108573 62500000 | + | 133497 25000000 | − | 70 | ( | 7 20 | + | 117 500000000 | ( | 652 | + | 70 | ) | ÷ | 2 | ) |
x≈0.317614 , keep 6 decimal places
