See the photo attached. The answer is x = 19, x = -1, so B.
Answer:

Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side
In this problem
M is the mid-point segment AB
N is the mid-point segment BC
so
Applying the Midpoint Theorem
MN is parallel to AC

we have that
---> given problem
substitute


Answer:
x is 7, y is -1
Step-by-step explanation:
x+7y=0
2x-8y=22 -> divide both sides by -2
x+7y=0
-x+4y=-11
Eliminate one of the equations by adding the equations.
11y=-11
y=-1
Substitue the value of y into te equation
x+7*(-1)=0
x=7
Answer:
2x+2y=6
Step-by-step explanation:
-4x + -2y = -18
2x + 3y = 24
2x + 2y = 6
Answer:
The equation should be 8(x+3)
