6B = 1446B/6 = 144/6B = 24Double Check your Answer6B = 1446(24) = 144144 = 144So 6B = 144 when B = 24.
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
-8 -6(-8) = 48
It is: b = -3
4d-2 equals 6b-4
-6b =15 -6b/-6 = 15/-6 b = -2.5
6B = 1446B/6 = 144/6B = 24Double Check your Answer6B = 1446(24) = 144144 = 144So 6B = 144 when B = 24.
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42

14c/100 -6b/100 = 102 and c + b = 2300 c = 2300 - b, so 14 x(2300 - b)/100 - 6b/100 = 102 (32200 - 14b) - 6b = 10200 32200 - 10200 = 6b + 14b 22000 = 20b b = 1100, c = 1200 Check: loss on bikes 66, profit on cards 168, net profit 102 QED
1-6b+7=14 8-6b =14 -6b =6 -b =1 b =-1
