b=7
the answer is a
A.
A=0 b=0 c=0
2a. (a, b and c are all equal.)
b=7
the answer is a
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
Whatever you do to one side of the equation (equals sign), you must do to the other: 43 - b = 24 ⇒ 43 - b + b = 24 + b ⇒ 43 = 24 + b ⇒ 43 - 24 = 24 + b - 24 ⇒ 19 = b So b is 19.
