Answer:
{ x = -13, y = -4
Step-by-step explanation using elimination:
Solve the following system:
{x - 3 y = -1 | (equation 1)
{x - 2 y = -5 | (equation 2)
Subtract equation 1 from equation 2:
{x - 3 y = -1 | (equation 1)
{0 x+y = -4 | (equation 2)
Add 3 × (equation 2) to equation 1:
{x+0 y = -13 | (equation 1)
{0 x+y = -4 | (equation 2)
Collect results:
Answer: {x = -13 , y = -4
