[ 1/1 Equation]
Work: Find the solution of equation 151.2×7.95-1.2×12 = 150c .
Question type: Equation
Solution:Original question:
756 5 | × | 159 20 | − | 6 5 | × | 12 | = | 150 | c |
| Left side of the equation = | 30051 25 | − | 72 5 |
| = | 29691 25 |
29691 25 | = | 150 | c |
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 :
| 150 | c | = | 29691 25 |
The coefficient of the unknown number is reduced to 1 :
| c | = | 29691 25 | ÷ | 150 |
| = | 29691 25 | × | 1 150 |
| = | 9897 25 | × | 1 50 |
We obtained :
| c | = | 9897 1250 |
Convert the result to decimal form :
| c | = | 7.9176 |
