Yes and they can be simplified to: b
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
9a + 3b - 11a - 4b = -2a -b
It is an expression that can be simplified to: 1-4b-5c
there is a sign missing -- if 4b +15 = 7b then 3b = 15 and b thus = 5 if 4b - 15 = 7b then 3b = -15 and b = -5
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
9a + 3b - 11a - 4b = -2a -b
1a+3b 2a+4b=3a +7b
3a + 4b - (-6a) - 3b? There is no equivalent because you did not make it an equality. However you could combine the numbers... 3a + 4b +6a -3b = 9a + 1b
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
It is an expression that can be simplified to: 1-4b-5c
there is a sign missing -- if 4b +15 = 7b then 3b = 15 and b thus = 5 if 4b - 15 = 7b then 3b = -15 and b = -5
4b
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
The like terms are sums of b terms and c terms separately 5c+2c+3c+4b 5c +2c + 4b + 3c => 10c + 4b
