[ 1/1 Equation]
Work: Find the solution of equation (1/2020)*(-3)+3 = 2*(-3)+b .
Question type: Equation
Solution:Original question:
| ( | 1 | ÷ | 2020 | ) | ( | - | 3 | ) | + | 3 | = | 2 | ( | - | 3 | ) | + | b |
| Left side of the equation = | 1 | ÷ | 2020 | × | ( | - | 3 | ) | + | 3 |
| = | 1 2020 | ( | - | 3 | ) | + | 3 |
| = | - | 1 2020 | × | 3 | + | 3 |
| = | - | 3 2020 | + | 3 |
| = | 6057 2020 |
6057 2020 | = | 2 | ( | - | 3 | ) | + | b |
| Right side of the equation = | - | 2 | × | 3 | + | b |
| = | - | 6 | + | b |
6057 2020 | = | - | 6 | + | b |
Transposition :
| - | b | = | - | 6 | − | 6057 2020 |
Combine the items on the right of the equation:
| - | b | = | - | 18177 2020 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
18177 2020 | = | b |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
| b | = | 18177 2020 |
This is the solution of the equation.
