Answer 2

Answer: MARK ME AS BRAINLIEST...PLEASEEEE..

Step-by-step explanation:

If 3 + 3 = 9 what is ?

Solution

3 + 3 = 9

3 - 9 = -3 (Collect like terms)

-6 = -3

= (-3)/(-6) (Divide both sides by the coefficient of )

∴ = ½ or 0.5

Check

If 3 + 3 = 9 ( = ½ or 0.5)

3(1/2) + 3 = 9(1/2) (substitute for = ½ or 0.5)

3/2 + 3 = 9/2

(3+6)/2 = 9/2

→ 9/2 = 9/2

∴ = ½ or 0.5
