3(2i-7)=15

Answer 1

To solve this equation, we will distribute the 3 to the terms inside the parentheses:

3 * 2i - 3 * 7 = 15

6i - 21 = 15

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

6i = 15 + 21

6i = 36

Finally, we divide both sides of the equation by 6 to solve for i:

i = 36/6

i = 6

Therefore, the solution to the equation is i = 6.
