A solution to an linear equation
cx + d = f is in the form x = a for some a, we call a the
solution (a might not be unique).
Rewrite your sentence:
x = 8, 8 is unique. So how many solution does it have?
Infinitely many: they are the same line!
It has two solutions and they are: x = 3.230396696 and x =
There are two solutions for x: x=11 and x=-7
One solution: x = -4
x = 4y = 1Only one solution:x = 1y = 0.25
