4b - 3
It looks like a meaningless collection of letter and numbers. There is no mathematical operator between 4b and 3, there is no sign of equality of or inequality.
The GCF is 1.

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
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-3+4b-2a-b-3+5=3b-1
3b - 3 - 4b = 5Combine the 3b and the -4b :-1b - 3 = 5 Add 3 to each side of the equation:-1b = 8 Multiply each side by -1 : b = -8
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
4b - 3
It looks like a meaningless collection of letter and numbers. There is no mathematical operator between 4b and 3, there is no sign of equality of or inequality.
To simplify the expression 2a - 3 + 4b - 2a - b - 3 + 5, we first combine like terms. Combining the terms with 'a', we have 2a - 2a = 0. Combining the terms with 'b', we have 4b - b = 3b. Combining the constants, we have -3 - 3 + 5 = -1. Therefore, the simplified expression is 3b - 1.
(a - b + 1)(a + b - 3)
5-4b = 1
3/4b
4b+3=15 4b=15-3 b=(15-3)/4 b=3
36 [1] b − 3 = a [2] 4(a + b) = 10a + b [3] 4a + 4b = 10a + b Substitute [1] (b − 3) for a in [3]: [4] 4(b − 3) + 4b = 10(b − 3) + b [5] 4b − 12 +4b = 10b − 30 + b [6] 18 = 3b [7] 6 = b [8] 3 = a
