Step-by-step explanation:
Simplifying
j = (2j + 3)
Reorder the terms:
j = (3 + 2j)
Remove parenthesis around (3 + 2j)
j = 3 + 2j
Solving
j = 3 + 2j
Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-2j' to each side of the equation.
j + -2j = 3 + 2j + -2j
Combine like terms: j + -2j = -1j
-1j = 3 + 2j + -2j
Combine like terms: 2j + -2j = 0
-1j = 3 + 0
-1j = 3
Divide each side by '-1'.
j = -3
Simplifying
j = -3
The value missed is 1 min / 60 seconds
<h3>What is unit conversion?</h3>
Units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.
To convert 720 seconds to hour,
First convert second to minutes divide by 60 and then again convert minutes to hour again divide by 60.
So,
720 seconds * ( 1 minutes / 60 seconds) * ( 1 hour / 60 minutes)
= 12 hours.
