3(2i−7)=15

1 answer

To solve the equation 3(2i - 7) = 15, we can start by distributing the 3 to the terms inside the parentheses:

3 * 2i - 3 * 7 = 15

6i - 21 = 15

Next, we can isolate the term with "i" by adding 21 to both sides of the equation:

6i - 21 + 21 = 15 + 21

6i = 36

Finally, we can solve for "i" by dividing both sides of the equation by 6:

(6i)/6 = 36/6

i = 6

Therefore, the solution to the equation 3(2i - 7) = 15 is i = 6.
