Answer:
Answer: {x = -2
, y = 5
Step-by-step explanation:
{x + 4 y = 18 | (equation 1)
{x + 8 y = 38 | (equation 2)
Subtract equation 1 from equation 2:
{x + 4 y = 18 | (equation 1)
{0 x+4 y = 20 | (equation 2)
Divide equation 2 by 4:
{x + 4 y = 18 | (equation 1)
{0 x+y = 5 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{x+0 y = -2 | (equation 1)
{0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -2
, y = 5
