2x+2y=16
<span>2x+6y=28
all you have to do is subtract to get rid of the 2x and solve for y
2x+2y = 16
-2x-6y = -28
---------------------------
0 -4y = -12
y = 3
now we got y we can plug in or do the systems of equation again and find x. lets do systems of equations again.
</span>2x+2y=16
<span>2x+6y=28
</span><span>
this time i am going to multiple the top by -3 and then add the equations hopefully it is clear why I multiple by -3
</span><span>
-3(2x+2y = 16)
2x +6y = 28
-6x - 6y = -48
</span>2x +6y = 28
------------------------
-4x + 0y = -20
x = 5

Answer:
I would not say that I hate police officers, but some of them are not being very good cops. Some are ok, but there are a lot who need to be fired.
Step-by-step explanation:
Answer:
9 + 10 = 21
69 + 420 = 69420
Step-by-step explanation:
these two angles are supplementary interior angles
therefore they add up to 180
16x+4 + 80 = 180
combine like terms
16x+84 = 180
16x = 96
divide each side by 16
x = 96/16
x = 6
