Question

X-3y=-1 x-2y=-5 in elimination

Answer 1

{ 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
