☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation (100+3.99)x = 100+2.95 .
Question type: Equation
Solution:Original question:
| ( | 100 | + | 399 100 | ) | x | = | 100 | + | 59 20 |
| Left side of the equation = | 100 | x | + | 399 100 | x |
| = | 10399 100 | x |
10399 100 | x | = | 100 | + | 59 20 |
| Right side of the equation = | 2059 20 |
10399 100 | x | = | 2059 20 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2059 20 | ÷ | 10399 100 |
| = | 2059 20 | × | 100 10399 |
| = | 2059 | × | 5 10399 |
We obtained :
| x | = | 10295 10399 |
Convert the result to decimal form :
| x | = | 0.989999 |
