5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
It is an equation in three unknown variables.
identity.
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
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.
-4b+2 = 18 -4b = 18-2 -4b = 16 b = -4
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.
