Answer:

See below

Step-by-step explanation:

Assumed you need to solve the system:

  • 12x - 2y = - 1
  • 4x + 6y = - 4

In order to solve this by elimination, triple the first equation and add the second one.

It will make the coefficients of y same with opposite signs:

  • -6y and 6y

When added together these cancel, leaving x as the only variable.
