Step-by-step explanation:
Answer:
x = 4 and y = 1
Step-by-step explanation:
3x+2y=14
2x-4y=4
We can solve them by canceling out one variable so we only have one variable left. Let's cancel out y by doubling the first equation. We get:
6x + 4y = 28
add that on to the second one and we get:
8x = 32
x = 4
We plug in x and get that:
y = 1
So in the end we get
x = 4 and y = 1
Answer:
-20
Step-by-step explanation:
y = 4x + b
-4 = 4(7) + b
-32 = b
y = 4x -32
r = 4(3) - 32
r = -20
