Find the solution of this system of equations. Separate the x- and y-values with a comma. x - 2y = -29 and x - y = -11
1 answer:
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
