Find the solution of this system of equations. Separate the x - and y-values with a comma. x - 2y = - 23 and x - y = 7

Solve the following system using elimination:

{x - 2 y = - 23 | (equation 1)

{x - y = 7 | (equation 2)

Subtract equation 1 from equation 2:

{x - 2 y = - 23 | (equation 1)

{0 x+y = 30 | (equation 2)

Add 2 * (equation 2) to equation 1:

{x+0 y = 37 | (equation 1)

{0 x+y = 30 | (equation 2)

Collect results:

Answer: {x = 37, y = 30
