Question

I need help getting these equations into coordinates so i can graph them

Answer 1

(4, -7)

Explanation:

3x + y = 5

x - 4y = 32

Solve the 2nd equation for x

x = 4y + 32

Plug this in for variable x into equation 1

3 · (4y + 32) + y = 5

Solve for y

3 · (4y + 32) + y = 5

12y + 96 + y = 5

13y + 96 = 5

13y = -91

y = -7

Plug this in for variable y into equation 2

x - 4(-7) = 32

x - (-28) = 32

x + 28 = 32

x = 4

Conclusion:

y = -7

x = 4

Answer 2

3x+2y=5

36x - 4y = 32
