2a-4b plus 4b-6a equals a plus b?
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
Simplify 7a plus 2a plus 1?
9a + 1
A plus b divide by 4a plus 4b?
1/4
How to solve b2 plus 3 equals 4b?
Since b2 is doubled by adding 3, b2 equals 3. 1/2 of that is b, hence b=1-1/2.
Factor these mr plus ns - nr - ms 00000 ab plus 4 plus a plus 4b?
ab + 4 + a + 4b factors to (a + 4)(b + 1)
SOLVE 4b-1 equals -4 plus 4b plus 3?
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.
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
What property is this 4b plus 1 equals 4b plus 1?
identity.
4 x b-1 plus -4 plus 4b?
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
2a-4b plus 4b-6a equals a plus b?
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
7a-17 equals 4a plus 1?
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
Simplify 7a plus 2a plus 1?
9a + 1
6b plus 7 5b -4b plus 1?
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.
A plus b divide by 4a plus 4b?
1/4
(4a-5) plus (3a plus 6)?
It is: 7a+1 when simplified
How do you solve 9a2-7a 1-2a2-5a 13?
I'll assume the missing signs are pluses. 7a^2 - 12a + 14
How to solve b2 plus 3 equals 4b?
Since b2 is doubled by adding 3, b2 equals 3. 1/2 of that is b, hence b=1-1/2.
