To solve the expression (7a + 4b - 1), you typically need to know the values of (a) and (b). Once you have those values, you can substitute them into the expression and perform the arithmetic to find the result. If no specific values are given for (a) and (b), the expression remains in its simplified form.

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.
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?
