Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system

If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
So your answer would be 7 because if you divide 21÷3 your answer would be 7.
Foil the equation; j*k, j*-5, 7*k, 7*-5, once you foil add like terms.
jk - 5j +7k - 35 is the final answer
Answer:
Step-by-step explanation:
X^4+x=0
X(X^3+1)=0
X(X+1)(x^2-x+1)=0
X=0, x=-1, x=(1+3^1/2i)x=(1-3^1/2i)
Answer:
9
Step-by-step explanation:
We can plug the value p=6 into the equation.
2*6-(6+3)/3=
12-9/3=
12-3=
9
