The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
It is the same as: 4b+665
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
identity.
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
2a + 4b
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
To get what is equivalent to 7 a plus 4b plus three you have to equate them to an equal sign.
