3i+2i−4=18i

infinite solutions
i = 5\
i = 4/13
i = -1/3
i = 8

The equation 3i + 2i - 4 = 18i can be simplified as:

5i - 4 = 18i

Subtracting 5i from both sides gives:

-4 = 13i

Dividing both sides by 13:

-4/13 = i

Therefore, the equation has a unique solution:

i = -4/13

To solve the equation 3i + 2i - 4 = 18i, let's collect all the "i" terms on one side and the constants on the other side.

On the left side, we have 3i + 2i - 4. Combining like terms, we get 5i - 4.

So the equation becomes 5i - 4 = 18i.

Now, let's isolate the "i" term by subtracting 5i from both sides:

-4 = 13i.

Finally, we can solve for "i" by dividing both sides by 13:

i = -4/13.

Therefore, the solution to the equation 3i + 2i - 4 = 18i is i = -4/13.
