The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
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
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
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.
The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
identity.
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
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
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
Oh, isn't that a lovely question! When you add b plus b plus b plus b, you are actually adding 4 "b's" together. So, it's like having 4 beautiful little b's all snuggled up together, creating 4b. Just imagine those b's painting a happy little equation on the canvas of mathematics.
36 -20 = 16
The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.
