Answer:

(-6,4)

Step-by-step explanation:

Solve the following system:

{4 y + 5 x = -14 | (equation 1)

2 y + x = 2 | (equation 2)

Subtract 1/5 × (equation 1) from equation 2:

{5 x + 4 y = -14 | (equation 1)

0 x+(6 y)/5 = 24/5 | (equation 2)

Multiply equation 2 by 5/6:

{5 x + 4 y = -14 | (equation 1)

0 x+y = 4 | (equation 2)

Subtract 4 × (equation 2) from equation 1:

{5 x+0 y = -30 | (equation 1)

0 x+y = 4 | (equation 2)

Divide equation 1 by 5:

{x+0 y = -6 | (equation 1)

0 x+y = 4 | (equation 2)

Collect results:

Answer: {x = -6 , y = 4
