Answer:
Can you restate the question, it is hard to solve with typos.
If you would like, it would also help to attach an image or picture of the question.
Answer:
B.
Step-by-step explanation:
So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.
-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
I hope this helps love! :)
Here we use the property, angles opposite to equal sides are equal,
(5x+27)=(45+3x)
5x-3x=45-27
2x =18
x=18/2
x=9
Answer is D. x=9
