Answer:
(StartRoot 2 EndRoot, negative 1) and (negative StartRoot 2 EndRoot, negative 1)
Step-by-step explanation:
we have
----> equation A
-----> equation B
solve by substitution
substitute equation B in equation A
solve for x
<em>Find the value of y</em>
For ---->
For ---->
therefore
The solutions are
(StartRoot 2 EndRoot, negative 1) and (negative StartRoot 2 EndRoot, negative 1)
