-12 + c = 19
Add 12 to both sides: c = 19+12 = 31
t = 4/5
the answer is a
6 + 12 - 5 = 13
b = sqrt32 or 4 root 2
It is an equation and the value of c works out as 8
a+b+c+d+e = 30 (i) c+e = 14 (ii) d+b = 1 (iii) a = 2b-1 (iv) a+c = 10 (v) By (i)-(ii)-(iii): a = 15 then, by (iv): b = 8 and by (v): c = -5 Also, b = 8 so by (iii): d = -7 and then by (i), e = 19
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=24 b=16 c=18
a = 20 b = 60 c = 100
There are four unknown variables and only three linear equations so there is not a unique solution. All you can do is to rearrange the four variables so that three of them can be expressed in terms of the fourth. For example: In terms of c, a = 6 - c/2 b = a - c = 6 - 3c/2 d = c
