4b-43 equal = -39
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
8b - 4b = 4b
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
4b - 1 = -4 + 4b + 3first, simplify and add together what you can.4b - 1 = -1 + 4b4b = 4bbecause 4b is always equal to 4b, the answer is infinite.
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5

4b-b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-4b+2 = 18 -4b = 18-2 -4b = 16 b = -4
The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
5-4b = 1
