If x + y = 2 and x - y = 6, solve for x and y.

Answer:

Step-by-step explanation:

Givens

x + y = 2

x - y = 6

Solution

Just add the two equations together. The y's will drop out.

x + y = 2

<u>x - y = 6 </u> Add

2x = 8 Divide by 2

2x/2 = 8/2 Combine

x = 4 Substitute x = 4 into the top equation

x + y = 2

4 + y = 2 Subtract 4 from both sides

4-4+y=2-4 Combine

y = - 2

Answer

x = 4

y = -2

$\bf \sqrt[3]{-1000p^{12}q^3}~~
\begin{cases}
1000=10^3\\
(-1)^3=-1\cdot -1\cdot -1\\
\qquad -1\\
p^{12}=p^{4\cdot 3}\\
\qquad (p^4)^3
\end{cases}\implies \sqrt[3]{(-1)^3(10)^3(p^4)^3q^3}
\\\\\\
(-1)(10)p^4q\implies -10p^4q$
