B=26 you just have to isolate the variable, so subtract 17 from 43 because the rule in algebra is that whatever you do to one side, you have to do to the other
b=7
the answer is a
4b
A.
A=0 b=0 c=0
b=7
the answer is a
4b
Yes because if 1+0=1 than 0 plus b equals b
a=24 b=16 c=18
a+b = 17a+c = 36 ----> c = 36 - ab+c = 25 ----> c = 25 - bSo since both are c, we say36 - a = 25 -bFrom this : 11 = a - bLook at 1st eqn: a + b = 17Now we have: a - b = 11 ----> a = 11 + bSo we can substitute that into a + b = 17 to make:(11 + b) + b = 1711 + 2b = 17So b = 3If b = 3, then a + 3 = 17 , so a = 14, 3 + c = 25, so c = 22So a=14, b=3, c=22, so a+b+c = 14+3+22 = 39
Because there is no way to define the divisors, the equations cannot be evaluated.
a= (+a) or a= (-) b= 2a b= 2a c= (-a) c= (+a)
A.
a+b=a+b
a = 20 b = 60 c = 100
A=0 b=0 c=0
