Jasmine Ferguson · Answer 1

Solve the following system using elimination:

{x - 2 y = - 29 | (equation 1)

{x - y = - 11 | (equation 2)

Subtract equation 1 from equation 2:

{x - 2 y = - 29 | (equation 1)

{0 x+y = 18 | (equation 2)

Add 2 * (equation 2) to equation 1:

{x+0 y = 7 | (equation 1)

{0 x+y = 18 | (equation 2)

Collect results:

Answer: {x = 7, y = 18
