Combine like terms on the left side.
-3y + 3y + 4 = 4
-3y and 3y add to 0, so you get
4 = 4
4 = 4 is a true statement, so there is an infinite number of solutions. Every real number is a solution of this equation.
Answer: Infinitely many

Answer:
-i
Step-by-step explanation:
i^0=1
i^1=i
i^2=-1
i^3=-i
i^4=1
This repeats so we want to see how many 4 factors of i there is in i^(23) which is 5 with a remainder of 3.
So i^(23)=i^3=-i.
i^(23)=i^(5*4+3)=(i^4)^5 * (i^3)=(1)^5 * (-i)=1(-i)=-i.
