Answer:
To  get system B, the SECOND equation in system A was replaced by the sum of that equation and the FIRST equation multiplied by FOUR. The solution to system B IS de same as the solution to system A
Step-by-step explanation:
x-y=3  equation 1
-2x+4y=-2   equation 2
so, multiplying by four the equation 1 we have
4x-4y=12   equation 3
later sum equation 3 and equation 2 we have
2x=10

Answer:
-0.1 and 0.1
Step-by-step explanation:
A fourth root is a number which multiplied by itself 4 times gives 0.0001.
Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.
0.1*0.1*0.1*0.1 = 0.0001
So the real fourth roots are -0.1 and 0.1.
