3(2i−7)=6i−21
3i+2i−4=18i
2i+3=2i−5
3(2i−7)=6i−21 - Solution: i = -3
3i+2i−4=18i - Solution: i = 1/7
2i+3=2i−5 - There is no solution to this equation.
are you sure
Apologies, I made a mistake in my response. Let me correct it:
3(2i−7)=6i−21 - There is no solution to this equation.
3i+2i−4=18i - Solution: i = -1/5
2i+3=2i−5 - There is no solution to this equation.
no
I apologize for the confusion. Let me provide the correct solutions:
3(2i−7)=6i−21 - Solution: i = 0
3i+2i−4=18i - Solution: i = -1
2i+3=2i−5 - There is no solution to this equation.
