The given system is
3x + 5y | = | 8 | ... (1) |
5x + 3y | = | 0 | ... (2) |
To eliminate y, we need to make the coefficients of y the same numerical value, but with opposite sign. We can do this as follows.
3x + 5y | = | 8 | -3 |
5x + 3y | = | 0 | 5 |
-9x - 15y | = | -24 |
25x + 15y | = | 0 |
Adding these equations then eliminates y.
