Answer:
See the "step by step explanation" for better understanding.
Step-by-step explanation:
Let's solve for x.
2x2+y2=18
Step 1: Add -y^2 to both sides.
2x2+y2+−y2=18+−y2
2x2=−y2+18
Step 2: Divide both sides by 2.
2x22=−y2+182
x2=−12y2+9
Step 3: Take square root.
x=√−12y2+9 or x=−√−12y2+9
Answer:
x=√−12y2+9 or x=−√−12y2+9
