Due today do not understand i will mark
what is the justification for each step in the solution of the equation?
fill in the empty boxes with the justification.

15x – 8 = −6 (2+8x) + 42

15x – 8 = −6 (2+8x) + 42 given
15x – 8 = −12 − 48x + 42 a.
15x − 8 = 30 − 48x b.
63x – 8 = 30 addition property of equality
63x = 38 c.
x = 38/63 division property of equality
