Work: Find the solution of equation 90a+94*1.3*a+86*1.3*a = 393453.91 .
Question type: Equation
Solution:Original question:
| 90 | a | + | 94 | × | 13 10 | a | + | 86 | × | 13 10 | a | = | 39345391 100 |
| Left side of the equation = | 90 | a | + | 611 5 | a | + | 559 5 | a |
| = | 324 | a |
| 324 | a | = | 39345391 100 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 39345391 100 | ÷ | 324 |
| = | 39345391 100 | × | 1 324 |
We obtained :
| a | = | 39345391 32400 |
Convert the result to decimal form :
| a | = | 1214.36392 |
