Answer:
See below
Step-by-step explanation:
<u>Assumed you need to solve the system:</u>
- 12x - 2y = - 1
- 4x + 6y = - 4
In order to solve this by elimination, triple the first equation and add the second one.
<u>It will make the coefficients of y same with opposite signs:</u>
When added together these cancel, leaving x as the only variable.
