Six take away B times five B plus 30 equals 1. This is a math problem.
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
b=7
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
Six take away B times five B plus 30 equals 1. This is a math problem.
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
b= -162
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
5b2 = 8b therefore 5b =8 therefore b = 1.6
5b + 3 = 10 - 3 - 3 5b = 7 5b/5 7/5 b= 1.5 There you go !
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
im sorry i keep trying to set up the problem exactly how it is on my paper...but it wont let me... :/ the answer is b=-4 though
b=7
really????? what grade are you in??? 5b b=3 so you plug in 3 for b giving you 5(3) then you multiply because its multiplication and you get 15
5b = 8 b = 8/5 or 1.6
