the 2nd expression is the answer
Equation 1) 4x + 2y = 8
Equation 2) 16x - y = 14
Multiply all of equation 2 by 2.
2) 2(16x - y = 14)
2) 32x - 2y = 28
1) 4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2

Answer:
No is false
Step-by-step explanation:
5 / 7 > 10 / 13 = False
8
This is actually fairly simple. If you take the x-1 and set it equal to 0 you get 1. And if you plug that value into the x you get 8, which is the remainder. This is called the remainder value theorem.
Answer:
C, 8,634.86
Step-by-step explanation:
Starting with 8,591.69
2.51% of 8,591.69 is 215.651419
subtract that from 8,591.69 and you get 8376.038581
3.09% of 8376.038581 is 258.819592153
258.819592153+8376.038581=8634.85817315
8,634.86 is your final answer
