Answer:
-8
Step-by-step explanation:
The answer is -8 because y=4 so 4-12=-8
It needs to be a number multiplicated by 10 with a round power. With your number, s
you should write it like that : 3.482000000x10^9 (if your zeros are significant, otherwise 3.482x10^9) OR 3.482000000G (for Giga=1×10^9)
From the secon equation, we can find x in terms of y by doing:
x = 2 + y
Pluggin this value of x in the first equation:
2(2 + y) - 2y = 14
4 = 14
We reached a false statement, which means that the given system of equations has no solutions. Another way to verify that would be by dividing the first equation by 2. Doing so, we would have equation 1: x - y = 7 and equation 2: x - y = 2, which is clearly impossible!
X/6 + 7 = 20
subtract 7 from each side
x/6 + 7 - 7 = 20 - 7
x/6 = 13
multiply each side by 6 to get x alone
x/6 • 6 = 13•6
x = 78
