SOLUTION: i=square root of -1 if 3i(2+5i)=x+6i, then x=

Question 671133: i=square root of -1 if 3i(2+5i)=x+6i, then x=
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
Distribute the 3i
3i(2) + 3i(5i) = x + 6i
...
cross(6i) + 15i^2 - cross(6i) = x
...
15i^2 = x
...
x = 15
x = 15(-1)
