7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
b=7
5b = 8 b = 8/5 or 1.6
-86
5b + 3 = 10 - 3 - 3 5b = 7 5b/5 7/5 b= 1.5 There you go !
If: 5b = 30 Then: b = 6
Six take away B times five B plus 30 equals 1. This is a math problem.
5b = 8 therefore b = 8/5 therefore b = 1.6
-b+5b-2b=2b
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
