What is the elimination method for 3x-2y=7 x+y=-1

x = -3/17 ,  y = 4/17

Step-by-step explanation:

Solve the following system:

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

{7 x + y = -1 | (equation 2)

Swap equation 1 with equation 2:

{7 x + y = -1 | (equation 1)

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

Subtract 3/7 × (equation 1) from equation 2:

{7 x + y = -1 | (equation 1)

{0 x - (17 y)/7 = -4/7 | (equation 2)

Multiply equation 2 by -7:

{7 x + y = -1 | (equation 1)

{0 x+17 y = 4 | (equation 2)

Divide equation 2 by 17:

{7 x + y = -1 | (equation 1)

{0 x+y = 4/17 | (equation 2)

Subtract equation 2 from equation 1:

{7 x+0 y = -21/17 | (equation 1)

{0 x+y = 4/17 | (equation 2)

Divide equation 1 by 7:

{x+0 y = -3/17 | (equation 1)

{0 x+y = 4/17 | (equation 2)

Collect results:  

 {x = -3/17 ,  y = 4/17
