Work: Find the solution of equation 11.63*3.14*0.55*（x-20） = （2*3.14*0.069*（170-x）/0.20067 ) .
Question type: Equation
Solution:Original question:
1163 100 | × | 157 50 | × | 11 20 | ( | x | − | 20 | ) | = | ( | 2 | × | 157 50 | × | 69 1000 | ( | 170 | − | x | ) | ÷ | 20067 100000 | ) |
| Left side of the equation = | 2008501 100000 | ( | x | − | 20 | ) |
2008501 100000 | ( | x | − | 20 | ) | = | ( | 2 | × | 157 50 | × | 69 1000 | ( | 170 | − | x | ) | ÷ | 20067 100000 | ) |
| Left side of the equation = | 2008501 100000 | x | − | 2008501 100000 | × | 20 |
| = | 2008501 100000 | x | − | 2008501 5000 |
2008501 100000 | x | − | 2008501 5000 | = | ( | 2 | × | 157 50 | × | 69 1000 | ( | 170 | − | x | ) | ÷ | 20067 100000 | ) |
| Right side of the equation = | 2 | × | 157 50 | × | 69 1000 | ( | 170 | − | x | ) | ÷ | 20067 100000 |
| = | 14444 6689 | ( | 170 | − | x | ) |
| = | 14444 6689 | × | 170 | − | 14444 6689 | x |
| = | 2455480 6689 | − | 14444 6689 | x |
2008501 100000 | x | − | 2008501 5000 | = | 2455480 6689 | − | 14444 6689 | x |
Transposition :
2008501 100000 | x | + | 14444 6689 | x | = | 2455480 6689 | + | 2008501 5000 |
x≈34.561205 , keep 6 decimal places
