Without information about j, the only possible answer is 3j + 15
-3j = 44.7 -j = 44.7 ÷ 3 -j = 14.9 j = -14.9
in algabreic terms, it is x
An equation where j = 3
An equation where j = 3
36.64
3j-13=11+2j 3j-13-2j = 11+2j-2 j-13 = 11 j-13 +13 = 11 + 13 = 24 so j = 24
3j + j = 4j
4
It has no real roots.
The discriminant is -439 and so there are no real solutions.
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
