Answer:
x = 1
y = -1
Step-by-step explanation:
y = 3x + 4y
3x + 3y = 0
So, we have 2 equations that are
3x + 3y = 0
x + 2y = -1
Times the second equation by -3
3x + 3y = 0
-3x - 6y = 3
-3y = 3
y = -1
Now put -1 in for y and solve for x
x + 2(-1) = -1
x - 2 = -1
x = 1
Let's check
1 + 2(-1) = -1
1 - 2 = -1
-1 = -1
So, x = 1 and y = -1 is the correct answer.
(_,-2)
Answer:
(3, -2)
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
(x, y) (__,-2)
-2 = -2r + 4
-2-4 = -2r
-6 = -2r
divide -2r on both sides
r=3 ---> x=3
(3,-2)
