Work: Find the solution of equation 0.75 = 1.75*0.54*(1.86-x) .
Question type: Equation
Solution:Original question:
3 4 | = | 7 4 | × | 27 50 | ( | 93 50 | − | x | ) |
| Right side of the equation = | 189 200 | ( | 93 50 | − | x | ) |
3 4 | = | 189 200 | ( | 93 50 | − | x | ) |
| Right side of the equation = | 189 200 | × | 93 50 | − | 189 200 | x |
| = | 17577 10000 | − | 189 200 | x |
3 4 | = | 17577 10000 | − | 189 200 | x |
Transposition :
189 200 | x | = | 17577 10000 | − | 3 4 |
Combine the items on the right of the equation:
189 200 | x | = | 10077 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 10077 10000 | ÷ | 189 200 |
| = | 10077 10000 | × | 200 189 |
| = | 3359 50 | × | 1 63 |
We obtained :
| x | = | 3359 3150 |
Convert the result to decimal form :
| x | = | 1.066349 |
