Solve using elimination.
-4x + 3y = -1
-4x + 5y = -7

x = -2 , y = -3

Step-by-step explanation:

Solve the following system:

{3 y - 4 x = -1 | (equation 1)

5 y - 4 x = -7 | (equation 2)

Subtract equation 1 from equation 2:

{-(4 x) + 3 y = -1 | (equation 1)

0 x+2 y = -6 | (equation 2)

Divide equation 2 by 2:

{-(4 x) + 3 y = -1 | (equation 1)

0 x+y = -3 | (equation 2)

Subtract 3 × (equation 2) from equation 1:

{-(4 x)+0 y = 8 | (equation 1)

0 x+y = -3 | (equation 2)

Divide equation 1 by -4:

{x+0 y = -2 | (equation 1)

0 x+y = -3 | (equation 2)

Collect results:

{x = -2 , y = -3

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
