It is the same as: 4b+665
4b+3=15 4b=15-3 b=(15-3)/4 b=3
The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
4b-15 = -11
4b + 3 = 15 First, Subtract 3 from both sides. -3 -3 4b = 12 Then, divide by 4 to get b by itself. 4 4 b = 3
15 ac + 20 bc + 6 ad + 8 bd =3a (5c + 2d) + 4b (5c + 2d) =(3a + 4b) (5c + 2d)
identity.
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
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.
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
1a+3b 2a+4b=3a +7b
