Answer:
x= -2, y = -2
Step-by-step explanation:
Solve the following system:
{2 y - 4 x = 4 | (equation 1)
{4 x - y = -6 | (equation 2)
Add equation 1 to equation 2:
{-(4 x) + 2 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by 2:
{-(2 x) + y = 2 | (equation 1)
{0 x+y = -2 | (equation 2)
Subtract equation 2 from equation 1:
{-(2 x)+0 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by -2:
{x+0 y = -2 | (equation 1)
{0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = -2
, y = -2
