It depends what x is...
-3 + 4.5 + 8 + 6 = -x-1 15.5 = -x-1 x-1 = -15.5 x = -1/15.5 x = -2/31
10 + 3(x + 2) = 31
3 plus 4 x plus 5 31 when simplified would give x = 23/4.
X = -31/8 = -3.875
13 + X = 31 Or 31 - 13 = X Ergo X = 18
What is the number of integral solution to x plus y plus z equals 100?
The equation does not have a solution.
x2-x+8=0 Discriminant D=(-1)2-4*1*8=-31 There's no solution in real numbers There are two solutions in complex numbers: x=(1 + i*sqrt(31))/2 or x=(1 - i*sqrt(31))/2
There is one solution. x = -3
You cannot since it has no solution.
It is a linear equation in x. It has a solution, which is x = -5
The given expression has no solution because without an equality sign it is not an equation that can be solved.
