Step-by-step explanation:
assuming j+12 us equal to 0
j+12=0
j+12-12=0-12 (subtract 12 on both sides)
so j is now equal to
j = -12
Add like terms. "Like terms" are those with the same constellation of variables.
.. terms with variable x: 5x +3x = (5 +3)x = 8x
.. terms with no variable: -9 -20 = -29
The simplified form is 8x -29.
