What should be added to 3x2 + xy +3y2 to obtain 4x2 +6xy ?
(1) x2 + 5xy – 3y2
(2) x2–5xy – 3y2
(3) x2 + 5xy + 3y?
(4) x2 +6xy – 3y?​

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

the answer is 11.2 (i know i’m late)
