Answer:
(5,2,2)
Step-by-step explanation:
-3x+4y+2z = -3
2x-4y-z=0
y = 3x-13
Multiply the second equation by 2
2*(2x-4y-z)=0*2
4x -8y -2z =0
Add this to the first equation to eliminate z
-3x+4y+2z = -3
4x -8y -2z =0
-------------------------
x -4y = -3
Take the third equation and substitute it in for y
x - 4(3x-13) = -3
Distribute the 4
x - 12x +52 = -3
Combine like terms
-11x +52 = -3
Subtract 52 from each side
-11x +52-52 = -3-52
-11x = -55
Divide by -11
-11x/-11 = -55/-11
x=5
Now we can solve for y
y =3x-13
y =3*5 -13
y = 15-13
y=2
Now we need to find z
2x-4y-z=0
2(5) -4(2) -z=0
10-8 -z=0
2-z=0
Add z to each side
2-z+z= 0+z
2=z
x=5, y=2, z=2

Answer:the slope is -1
Step-by-step explanation:
Comparing them equation to
y=mx+c where m is there slope
y=-x-4 the slope is -1
Answer:
y=f−11/c
Step-by-step explanation:
cy+11=f
Step 1: Add -11 to both sides.
cy+11+−11=f+−11
cy=f−11
Step 2: Divide both sides by c.
cy/c=f−11/c
y=f−11/c
Answer:
y=f−11/c i think
