x2 + 3x + 3 = 0 doesn't factor neatly. Applying the quadratic formula we find two imaginary solutions: (-3 plus or minus the square root of -3) divided by 2
x = -1.5 + 0.8660254037844386i
x = -1.5 - 0.8660254037844386i
where i is the square root of negative 1

In the equation 3x plus 7 equals 13, x is equal to 2.
It is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13

There are no real solutions because the discriminant of the quadratic equation is less than zero.
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
x = 5 or x = 6
is an equation of a line in plane coordinate geometry. The coordinates of every point on that line satisfy the equation so there are an infinite number of solutions to the equation.
