First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe
Answer: none
1) combine like terms: 4x + 8 = 4x - 13
2) Add 13 to both sides (addition property of equality)
3) Subtract 4x from both sides (subtraction property of equality)
4) 21 does not equal 0
Answer:
