[ x = 11 ] is.
An algebraic equation has (at least one) variable, usually called x. To solve the equation means to figure out the value of x. For example, in the equation x + 4 = 7 the solution is x = 3, because 3 + 4 = 7.

Given the equation 3x + 4 = 7, will there ever be more than one solution for x?
If: 3x+8-x = 5x-4 Then: x = 4
4 x z = 28 z = 28/4 z = 7

Solution: x = 1/4 and x = -3.

4 x z = 28 z = 28/4 z = 7
Is (7, 9) a solution to the equation y = x?
Another solution for x+y = 7 is y = -x+7
How about x+4 = 0 ?
A number that makes an equation true is a solution. If there is more than one answer to an equation (such as an equation like): (x-2)(x+4)=0 then it is called a solution set (and in this case would be x={-4, 2}).
-4
Because it's not an equation
